Abstract

A strong CH3OH FIR laser line at 123 gm, more than twice as powerful as the well-known line at 119 gm, has been found by optically pumping methanol vapour with the newly discovered 9P(20) hot band line of the CO2 laser. High-resolution Fourier transform spectroscopic results reveal this new line to be the (nIK,J)v = (018,14)C0 Ã¢â‚¬â€* (027,13r0 transition, pumped in the R(018,13) CO-stretch transition of CH3OH. This is the same energy level system to which the 119 gm line belongs. The spectroscopic wavenumber of the new line is in excellent agreement with the frequency measured by heterodyning.
