Abstract Analysis of measurements of vibration‐rotational transitions of 209 Bi 1 H and 209 Bi 2 H in electronic ground state × 0 + yielded values of coefficients of radial functions that represent the intemuclear potential energy and adiabatic and nonadiabatic rotational effects of the hydrogen atomic centre. Both these effects have exceptionally large magnitudes, tentatively attributed in part to interaction with nearby electronically excited state A 1. The maximum range of validity of radial functions of BiH is 1.49 ≤ R/10 −10 m ≤ 2.4; the equilibrium intemuclear distance R e is (1.8041955 ± 0.186) × 10–10 m.
