Popis:	The 22 K sub-bands, belonging to the v 1 + v ±1 6, v 3 + v ± 5 + 2v 0 6 and v 3 + v ±1 5 + 2v ±2 6 rovibrational bands of monoisotopic CH3 79Br, have been identified. An RMS standard deviation of about 0·020 cm-1 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) v 1 + v ±1 6, and v 3 + v ±1 5 + 2v 0 6, (ii) v 1 + v ±1 6 and v 3 + v ∓1 5 + 2v ±2 6 and (iii) v 3 + v ±1 5 + 2v 0 6 and v 2 + 2v 3 + v ±1 5 and (b) Coriolis resonances between the v 2 and v 5 modes, was used.
