Abstract
Raman displacements, estimated intensities and depolarization factors have been obtained for CH3CH2C≡CH, CH3(CH2)2C≡CH, CH3(CH2)3C≡CH, CH3CH2C≡CCH2CH3, CH3(CH2)2C≡C(CH2)2CH3, and CH3(CH2)4C≡CCl. The data obtained in the 2200 cm−1 region 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 cm−1 in the spectrum of 1‐butyne and the absence of the line near 2245 cm−1 in the spectrum of 4‐octyne. Introduction of the Cl atom in the last compound radically modifies the spectrum in this region.Keywords
