Notes:
Isotopic species of the HeH+ molecular ion provide an excellent testing ground for studying isotopic dependence of vibration–rotation constants because of the small masses of He and H isotopes. We have observed infrared spectra of the hot band v=2←1 of HeH+ and fundamental bands of isotopic species HeD+, 3HeH+, and 3HeD+, and obtained the Dunham coefficients Ykl, and the isotopically independent parameters Ukl, ΔHekl, and ΔHkl.
