The advantages of the neon matrix to the vibrational study of van der Waals and hydrogen bonded molecular complexes

Résumé

Studies of weakly bonded complexes formed between water and atmospheric molecules can give important information on molecular interactions in atmospheric chemistry. Van der Waals and hydrogen bonded molecular complexes have motivated both theoretical and experimental studies. In the absence of gas phase data, essentially in the near and far infrared, matrix isolation can bring pertinent information on several-quanta transitions or weak fundamentals. Also, the use of a more inert matrix, neon, causes less perturbation than N2 or Ar on the frequencies shifts. The purpose of this communication is to illustrate the advantages of the matrix isolation with neon to study the van der Waals and hydrogen bonded molecular complexes. Some examples are done with Ln-(H2O)m complexes, noted n:m, with L= N2O, OCS, diacetyl, CO2, oxirane, and H2O.
