摘要：

We report on high-accuracy Fourier transform measurements of the far-infrared spectrum of (CO)-C-12-O-18, between 0.87 and 2.7 THz (32.9-91.2 cm-1). Precise rotational constants are determined and transition frequencies up to J = 35-34 are given (with an accuracy better than 5 x 10(-7), along with the previously available transition frequencies for (CO)-C-12-O-16 and (CO)-C-13-O-16.
