The IR spectrum of the ν1 band of natural bromochloromethane (CH2BrCl) has been recorded at a resolution of 0.008 cm−1 in the region 2940-3060 cm−1 on a BOMEM DA3.002 Fourier-transform spectrometer. The rovibrational analysis on the strong Q branch of this B-type band has been performed in the prolate symmetry top approximation due to the fairly small difference between constants B and C. A normal linear least-square fitting of the identified P,RQK(J) clusters provided the corresponding excited state molecular parameters for three of the four naturally existing isotopomers of bromochloromethane with a standard error of about 0.02 cm−1
