Combined subdoppler laser-Stark and millimeter-wave spectroscopies: Analysis of the ν6 band of CH335Cl

New measurements and global analysis of rotational spectra of Cl-, Br-, and I-benzene: Spectroscopic constants and electric dipole moments

“…The current results are compared in Fig. 2 with precise gas-phase values available for the hydrogen halides, HF [24], HCl [25], HBr [26], HI [27], methyl halides, CH 3 F [28], CH 3 Cl [29], CH 3 Br [30], CH 3 I [31], and tertiary butyl halides [14]. The dipole moment is plotted as a function of the polarizability of the halogen atom [33], which is a property that plays a key role in the evolution of the molecular dipole moment.…”

The ν6Band of Methyl Chloride Revisited by Fourier Transform Spectroscopy

“…(9), was given by Wlodarczak et al (10). The results we obtain for the excited To our knowledge, the infrared absorption spectrum of the n 6 band of methyl chloride near 1018 cm 01 has been state will be compared with those obtained in these three references (1,9,10).…”

“…The Dl Å {2, Dk Å |1 interaction is not considered since the weights were taken as 0 or 1. They were fixed equal to zero corresponding parameters are not independently attainable for lines which were very asymmetrical, due to overlapping, (10,22,23). This is the same reason why a term in q K (K or for which the experimental minus observed wavenumber 0 1) 2 was not introduced in the development of Eq.…”

The results we obtain for the excited To our knowledge, the infrared absorption spectrum of the n 6 band of methyl chloride near 1018 cm 01 has been state will be compared with those obtained in these three references (1,9,10). To be complete, let us note also that studied by Doppler limited spectroscopy only by Deroche and Graner in 1984 (1), with the purpose of deducing the microwave spectra and molecular constants in the £ 6 Å 1 state were reported for both molecules in 1981 by Dubrulle molecular constants needed to identify the far infrared laser lines which were optically pumped by CO 2 lasers (2-5).…”

“…zak et al (10), then the standard deviation on the wavenumThe values of the upper state molecular constants are listed bers is multiplied by a factor of more than 6. Under these in Table 4 for CH 3 35 Cl and in Table 5 for CH 3 37 Cl.…”
