摘要：

We report on high accuracy absorption spectroscopy of CH3OH in the far infrared. In addition to 22 transitions in the ground state, we have measured the frequency of the (n, t, J, K), (0, 1, 16, 8) → (0, 2, 15, 7) transition in the ϕ excited vibrational level, which is responsible for the laser emission at 119 μm. The measured frequency is 2 522 782.57(10) MHz at “zero pressure,” with a pressure shift of 6.1(32) kHz /Pa (0.805(420) MHz/torr). An accurate remeasurement of the laser emission frequency has also been performed, and the results are in good agreement. © 1990 IEEE
