Transitions of the a-type and b-type spectra of $CH3CD2Cl$, $CH2DCH2Cl$, $C13H3CH2Cl$, and $CH3C13H2Cl$ have been measured in the 8 to 30 kme region of the microwave spectrum. The data combined with previous $results1,2$ on the spectra of $CH3CH2Cl35$, $CH3CH2Cl37$, and $CH2DCH2Cl35$ have enabled a complete determination of the structure by the substitution method. The following parameters are obtained:[FIGURE] The chlorine quadrupole coupling constants have been reanalyzed and will be discussed.
