Calculation of the vibrational spectra of methyl vinyl sulfide and its deuterated derivatives

UV Laser‐Induced Gas‐Phase Copolymerization of Carbon Disulfide and Ethene

“…[22] (We note that the solid obtained upon laser irradiation of ethene shows an absorption at 1 614 cm À1 that is assigned to a n(C C) band in a non-conjugated system.) The bands at 1 584, 1 509, 1 442, and 1 376 cm À1 correspond to a n(C C) double bond attached to different numbers of S atoms and their assignment was possible because of the literature data on aliphatic monoalkylthioethenes, [24,25] 1,1-bis(alkylthio)ethenes, [26,27] 1,2-(bisalkylthio)ethenes, [28] tris(alkylthio)ethenes, [29] and tetrakis(alkylthio)ethenes. [29] We compare these bands with that observed for the deposit fromCS 2 at1 470cm À1 anddiagnosticforan(C C)double bond attached to four S atoms (e.g., 4,5-bis{[2-(methylthio)-ethyl]thio}-1,3-dithiiole-2-thione, 1 453 cm À1 , [30] 4,4 0 ,5,5 0 -tetrakis(decylthio)tetrathiofulvalene, 1461 cm À1 [31] ).…”

UV Laser Chemical Vapor Deposition of Nano‐Chained Copolymer from Carbon Disulfide and Ethene

“…(We note that the solid obtained upon laser irradiation of ethene showing absorption at 1 614 cm À1 is a sign of the n(C C) band in a non-conjugated system.) The bands at 1 585, 1 511, 1 441 and 1 375 cm À1 correspond to n(C C) double bond attached to different number of S atoms and their assignment was possible due to the literature data on aliphatic monoalkylthioethenes, [26,27] 1,1-bis(alkylthio)ethenes, [28,29] 1,2-(bisalkylthio)ethenes, [30] tris(alkylthio)ethenes [31] and tetrakis(alkylthio)ethenes. [31] We compare these bands with that observed with the deposit from CS 2 at 1 470 cm À1 and diagnostic to n(C C) double bond attached to four S atoms (e.g., 4,5-bis{[2-(methylthio)ethyl]thio}-1,3-dithiole-2-thione, 1 453 cm À1 , ref.…”
