The european congress on molecular spectroscopy - EUCMOS

The EUCMOS meetings can be traced back to 1947, when Reinhard Mecke organized a congress under the auspicies of the informal European Molecular Spectroscopy Group, in Konstanz. However, the meeting that has since become regarded as the first EUCMOS was organized by Ernst Miescher in Basel, in 1951. Since then, every two years an EUCMOS meeting has been held in different places in Europe. The scientific excellence of the series makes EUCMOS one of the most important events in the field of Molecular Spectroscopy.

A brief history of EUCMOS updated

The European Molecular Spectroscopy Group, which was constituted informally after the Second World War to bring together spectroscopists from across Europe, met for the first time in Konstanz in1947 [1]. Reinhard Mecke was at the time working in temporary accommodation at Wallhausen, a small village on the shores of Lake Constance, and the meeting (initiated by invitation of Professors Lecomte and Kastler from Paris) was attended by French, German and Austrian spectroscopists [2].
However, the meeting which has since become regarded as the first of the EUCMOS series was organised under the auspices of Ernst Miescher in Basel in 1951, followed every two years by conferences in Paris (1953), Oxford (1955), Freiburg (1957), Bologna (1959), Amsterdam (1961), Budapest(1963), Copenhagen (1965) and Madrid (1967). As is often the case, the titles and numbering of the early conferences were not consistent with later practice. The 1955 Oxford conference was described in an account by Harold Thompson [1] as a (fourth) meeting of the European Molecular Spectroscopy Group. In the published proceedings of the 1959 Bologna meeting [3], the conference was referred to as the IVth Meeting on Molecular Spectroscopy of the European Committee on Molecular Spectroscopy. The plenary lectures of the 1961 Amsterdam meeting were published in Pure and Applied Chemistry under the now customary title (Vth) European Congress on Molecular Spectroscopy [4], and the following meeting in Budapest in 1963 was designated at the time as EUCMOS VI. However, the publications in Pure and Applied Chemistry arising from the 1965 Copenhagen and 1967 Madrid meetings [5,6] were entitled EUCMOS VIII and IX, thus by 1965 the retrospective numbering sequence shown in Table 1 had become established.

In 1969 a more specialized EUCMOS meeting, devoted to solid state optical spectroscopy, was held in Liége [7]. In the Preface to the proceedings volume, B. Rosen (the Congress President) described the arrangement of EUCMOS meetings:
"In the course of a congress, ad hoc groups of colleagues make proposals as to where the next congress shall be held, and, according to a tradition which is already old and venerable, the final decision is made by a committee presided over by Professors Alfred Kastler, Jean Lecomte and Sir Harold Thompson" (the other pioneer of the EUCMOS meetings, Reinhard Mecke, died in 1969).
The next meeting was not held until 1973, when it was organised in Tallinn and similarly concentrated on solid state spectroscopy. The plenary lectures were again published in Pure and Applied Chemistry [8].
The 1975 meeting in Strasbourg was devoted to the molecular spectroscopy of dense phases [9] and can be regarded as effectively the last organised by the founders of EUCMOS in the manner described by Rosen (Jean Lecomte died in 1979 and Sir Harold Thompson in 1983).
The International Committee was considerably expanded at the 1977 meeting in Wroc?aw and elected as its President Orville-Thomas who, supported by Müller and Ratjaczak, continued to uphold the tradition of an independent EUCMOS organisation. A further innovation, following the 1979 meeting, was the inclusion of overseas representatives on the International Committee in recognition of the significant number of scientists from outside Europe attending the conferences (Table 2). Also starting with EUCMOS XIII (1977), the proceedings of each conference have been published in the Journal of Molecular Structure [10-30].
The regular pattern of meetings every two years was perturbed for the second time in 1991 when EUCMOS XX, which was due to be held in Zagreb, had to be cancelled because of the civil war in Yugoslavia. The following meeting, in Vienna, was brought forward by a year and the meetings have since been held in the even years.

At EUCMOS XXII held in Essen (1994), Orville-Thomas retired as President of the International Committee and Barnes was elected to this post. During his mandate, 11 conferences of the series were held, included the one organised in Coimbra in the Year 2000 (EUCMOS XXV). Over 370 scientists from 48 countries took part in that meeting, where the opening lecture was delivered by Sir Harold Kroto, the 1996 Chemistry Nobel Prize winner [22]. During this period, the International Committee integrated the organisers of the different meetings for a period of four years, in an automatic rotating scheme. The proceedings continued to be published in dedicated special issues of the Journal of Molecular Structure [23-30].

In EUCMOS XXXIII (2016, Szeged) Barnes retired as President of the International Committee and Fausto (vice-President since EUCMOS XXVII, Cracow, together with Ratajczak) was elected to this position. It was a coincidence that the new President had already been chosen as the organiser of the next EUCMOS meeting to be held in Coimbra from 19-24 of August 2018 (EUCMOS XXXIV). Ratajczak and Schmitt are the current vice-Presidents of the International Committee.
For 70 years, EUCMOS has been at the service of spectroscopy in Europe and in the world. The flourishing EUCMOS history is, probably, the best example of how an independent association of scientists can result in a long-term successful series of events characterized by the excellence of its scientific contents, sustained support to developments in spectroscopy, and stimulus to young researchers… all this, in the very characteristic warm and stimulating social environment of the EUCMOS meetings.
