“…The hydrogen molecule, being a very small and simple molecule, is an excellent model substance for matrix-isolated studies; it has already been described for matrix-isolated CS2 (2). Moreover, the molecular and spectroscopic data of hydrogen are well known (3).…”

The hydrogen molecule is treated as a model substance for matrix-isolation effects. Raman investigations are made concerning the influence of matrix material on the various modes of hydrogen. The opposite interaction, how the defect influences modes of the matrix, is the object of the following paper.For the doublet in the vibrational range of hydrogen in rare-gas solids, an assignment to Ql(0) and Q2(l) is made and well substantiated. In addition to matrix-shift considerations, temperature influences, orrho-para investigations, and aggregation effects, different sites are observable in the nonspherical matrices, N2 and 0 2 , with a restriction of free rotation in nitrogen.La molCcule d'hydrogkne est traitCe comrne une substance modkle pour les effets d'isolation de matrice. Des etudes de spectroscopic Raman ont CtC faites concernant l'influence du matCriau matriciel sur les diffkrents modes de l'hydrogkne. L'interaction opposCe-l'influence des dCfauts sur les modes de la matrice-est traitCe dans I'article suivant. Pour le doublet dans le spectre vibrationnel de l'hydrogkne, une attribution a Q1(0) et Q l ( l ) est faite et bien prouvCe. En plus des considCrations de dCcalage matriciel, des influences de la temperature, des investigations ortho-para et des effets d'aggrkgation, diffkrents sites sont observables dans les matrices non spheriques, N2 et 02, avec une restriction de rotation libre dans l'azote.

“…2, cannot be explained by the thermolysis products proven so far, but can be attributed tentatively to a stretching mode of CS 2 . A set of frequencies at 1529 for the stretching mode, and at 397 and 395 cm À1 for the bending mode of CS 2 in argon matrices have been reported, 24 but unfortunately the bands due to the bending mode were below our detection limit (400 cm À1 ). As another reaction product acetonitrile, CH 3 CN, can be identified showing a characteristic n(CN) stretching vibration at 2259 cm À1 .…”

A series of high-vacuum thermolysis experiments with alkyldithio thiadiazoles was performed between ambient temperature and 900 degrees C to investigate the thermal stability of thiadiazole type lubricant additives. The thermolysis products were trapped by matrix-isolation techniques and characterized by IR spectroscopy. Thermolysis of 2-(tert-butyldithio)-5-methyl-,3,4-thiadiazole (TB1) gave 2-methylpropene, isothiocyanic acid (HNCS), 2-mercapto-5-methyl-1,3,4-thiadiazole (McMT), hydrogen cyanide (HCN), carbon disulfide (CS2), acetonitrile (CH3CN), and elemental sulfur S(x) [x = (2), 4, 6, 8]. A decomposition mechanism is discussed explaining the temperature-dependent composition of product mixtures, and a general precursor concept for organosulfur type anti-wear additives is presented.
