摘要：

The vibration-rotation spectrum of the υ4 + υ8 - υ8 band for CH3NC has been observed and measured with an interferometric spectrometer with a spectral resolution of 0.004 cm-1; 175 transitions were assigned to the P(J, k, l) branches spanning J = 5-29 and k = 3-8. Spectroscopic constants for the υ4 + υ8 state were obtained through a least-squares fit by explicitly taking account of the l-resonance. The validity of the additivity rule of molecular constants is discussed. Small anomalies detected in the K = 3 and 4 subbands of the υ4 + υ8 - υ8 band were ascribed to a rotational resonance (Δl = ∓1, Δk = ±2) between the υ4 + υ8 and 4υ-28 states. © 1993 Academic Press, Inc.
