Abstract
The bending fundamental bands of HCCCN, υ5 and υ6, have been recorded in the region from 470 to 700 cm-1 with a resolution of 0.04 cm "' using an FT spectrometer. The band centers have been determined precisely; υ5 = 663.2220(10) and υ6 = 498.8022(10) cm-1 . From the obtained effective rotational constants, the sign o f the /-type doubling constants has been determined to be positive for the υ5 = 1 and υ6 = 1 vibrational states.Keywords
