The pure rotational ( S ‐branch) and vibration‐rotational ( Q ‐branch) Raman spectra of 1 H 2 , 1 H 2 H and 2 H 2 have been recorded photographically and analysed with a precision greater than that achieved in earlier investigations to produce values of the bond lengths. From a combination of these results and those obtained from the species 2 H 3 H, 1 H 3 H and 3 H 2 a mean value of the bond length in the equilibrium configuration of r e = 74.151±0.001 pm has been obtained.
