A HIGH-RESOLUTION STUDY OF THE 14.4-μM INFRARED BAND OF DEUTEROFLUOROFORM

Abstract The FT-IR spectrum of the ν3 parallel band of deuterofluoroform has been recorded at a resolution of 0.0045 cm−1. Nine independent spectral parameters were determined which reproduce some 650 observed wavenumbers with a standard error of 3 × 10−4 cm−1. The constants derived for the ν3 band are (in cm−1): ν0 = 694.2822(3); B0 = 0.3309321(9); B3 = 0.3302464(11); αB = 6.859(10) × 10−4; αC = 1.429 × 10−4; D3J = 3.168(3) × 10−7; D0J = 3.188(3) × 10−7; DJK3 = 4.766 × 10−7; DJK0 = 4.864 × 10−7; and DK0 − DK3 = 2 × 10−10.
