摘要：

A number of CH3CN ground state rotational transitions from 0.5 to 1.5 THz have been accurately measured by means of a CO2 laser difference frequency spectrometer. The measurements are one order of magnitude more accurate than the previous FTS measurements and cover a larger range than the previous high-resolution submillimeter FIR studies. The measurements up to J = 80 with an accuracy ranging between 5 × 10-8 and 2 × 10-7 have led to an improvement in the molecular constants, especially the high-order terms. © 1990.
