Abstract

Two extensive band systems of HD and

D_{2}

3 d {}^{1}Σ \to 2 p {}^{1}Σ

and

3 d {}^{1}Π \to 2 p {}^{1}Σ

are given and described and a few weaker and less complete systems ending on the same state. The rotational constants of

2 p {}^{1}Σ

can be corrected with the help of the isotopic relations and satisfactory values obtained. There is at present, however, no way to obtain very accurate values of the vibrational constants for any state of the hydrogen molecule. The

H_{2}

constants of all the states concerned have been recalculated and from the comparison of the three isotopic molecules much can be learned about the reliability of the constants and other properties of the states.

3 d {}^{1}Π^{-}

is strongly decoupled but free from prominent perturbations, whereas

3 d {}^{1}Σ

and

3 d {}^{1}Π^{+}

are strongly perturbed.
