The coefficients C j , j ≤ 9, defining the potential‐energy V(z) and coefficients of two other radial functions related to adiabatic and nonadiabatic effects have been determined for AlH in the electronic ground state X 1 ∑ + by a direct fit to the published frequencies and wavenumbers of vibration‐rotational transitions of 27 Al 1 H and 27 Al 2 H. The functions are valid in the range of internuclear distance/10 −10 m [1.24, 2.60]. Some trends in the spectral properties of the group 13 hydrides AlH, GaH, InH and TlH are discussed. The possibility of determining the rotational magnetogyric factor g j from the available data of only wavenumbers of vibration‐rotational transitions is considered; an approximate value g j ∼ −2.25 is deduced for 27 Al 1 H.
