✦ Synopsis

about 230 kHz away. This measurement has been taken at a pressure of A novel technique of high-resolution spectroscopy has recently been about 0.2 Pa, so the linewidths are almost Doppler-limited and there is no developed in our laboratory (1). We used a new version of the IR-mmwave hope of improving the resolution without resorting to Doppler-free methods. double-resonance method to study the Β£ 6 Γ… 1 excited vibrational state of An example of the ''resonant'' case is shown in Fig. 1c, which displays CH 3 I and to measure the frequency of rotational and vibrational transitions the measurement of the absorption spectrum as recorded when the laser is at sub-Doppler resolution (2). In this letter we describe the first application chopped and tuned very close to the IR resonance of line Y.

A set of 26 new measurements have been recorded by a Doppler-free double-resonance technique, with a relative accuracy of about 10(-8). These data are combined to previous FTIR measurements to refine the molecular constants of 12CH3I. All the available literature data have been revisited, a few assi

The rotational analysis in the ground vibrational state has been carried out for CH 3 D by using the ground state combination differences. More than 1500 allowed and 2500 forbidden transitions from the fundamental bands 3 , 5 , and 6 were used to determine 12 rotational parameters, which reproduce t
