摘要

Raman displacements, estimated intensities and depolarization factors have been obtained for CH3CH2Ctrpbnd;CH, CH3(CH2)2Ctrpbnd;CH, CH3(CH2)3Ctrpbnd;CH, CH3CH2Ctrpbnd;CCH2CH3, CH3(CH2)2Ctrpbnd;C(CH2)2CH3, and CH3(CH2)4Ctrpbnd;CCl. The data obtained in the 2200 cmminus;1region were 2068(1)P, 2118(10)0.5, 2158(3)0.5; 2064(0), 2118(10)0.5; 2071(0), 2094(0), 2118(10)0.4; 2200(1)P, 2231(9)0.4, 2247(8)0.4, 2301(6)0.4; 2234(10)0.5, 2292(6)0.5; 2148(1)P, 2194(1)P, and 2243(10)0.4, respectively. Unusual features are the appearance of the second strong line at 2158 cmminus;1in the spectrum of 1hyphen;butyne and the absence of the line near 2245 cmminus;1in the spectrum of 4hyphen;octyne. Introduction of the Cl atom in the last compound radically modifies the spectrum in this region.
