Vibration-rotation spectra of ethane and deuteroethanes. The ν2 band of CH 3CD 3
Abstract
The ν2 band of CH 3CD 3 has been measured under an effective resolution of 0.04 cm -1. About 400 transitions observed in the region from 2130 to 2060 cm -1 have been identified as due to the ν2 fundamental band. The least-squares analysis of these transitions yields the band constants: ν0 = 2089.957, B' = 0.548937, DJ' = 6.97 × 10 -7, DJK' = 1.92 × 10 -6, A' - A″ = -0.01158, and DK' - DK″ = 1.30 × 10 -6 cm -1. The ground-state constants B″, DJ″ , and DJK″ are fixed to the values obtained from microwave spectroscopy.
