Alamichel (1992) Anharmonic resonances between the v 1 + v ±1 6 , v 3 + v ±1 5 + 2v 0 6 and v 3 + v ∓1 5 + 2v ±2 6 vibrational bands of CHThe 22K sub-bands, belonging to the vx + v~ l, v3 + v( + 2v ~ and v3 + v5 xl + 2v~ 2 rovibrational bands of monoisotopic CH379Br, have been identified. An RMS standard deviation of about 0-020cm -~ has been achieved by a least squares fit over 619 lines belonging to these 22 sub-bands. For this purpose, a model taking into account (a) anharmonic resonances between (i) Vl + v~ 1, and v3 + v~ l + 2v~ + v6~ andv3 + v~ l + 2vn~2and(iii)v3 + v~ l + 2v~ v2 + 2v~ + v~ 1 and (b) Coriolis resonances between the v2 and v5 modes, was used.
