Abstract

We have measured the frequency of the 187 μm laser emission of methyl fluoride when optically pumped by the 9.17 μm R10 line of the12C18O2 laser, and find it to be f=(1 604 647.7±0.3) MHz. The result is of interest for comparison with recent 9-μm band measurements on methyl fluoride using diode lasers.
