The millimeter-wave spectrum of CF3Cl

Supersonic free-jet quantum cascade laser measurements of ν4 for CF335Cl and CF337Cl and FTS measurements from 400 to 1260cm−1

“…6). The band center given by the present work agrees with that of Bürger et al [21] and the B 5 and q 5 values agree with those given by the microwave measurements of Carpenter et al [34].…”

“…Both P-and R-branches were observed up to kl = +16 and the resulting ground state combination-differences compared quite well with those given by the ground state constants. The upper state constants also agreed quite well with those measured by Carpenter et al [34] although we had to add some higher order constants in order to get a good fit. Fig.…”

“…The assignments were also verified through the agreement of the combination-differences, DF 2 00 (J), with the ground state constants given by Carpenter et al [34]. If one carefully notes in Fig.…”

“…This deduction was based on the effects of the l-type resonance that couples the two components. The l-type resonance calculation was possible because the value of q 5 was given by the microwave analysis of Carpenter et al [34]. Cl.…”

“…Neither the m 3 nor m 6 states have been directly measured although a low resolution measurement was made of the m 1 -m 3 transition. The rotational constants for the ground state and for the m 6 and m 5 states have been determined by Carpenter et al [33,34] and Harder et al [35] from the analysis of microwave measurements.…”
