Absorption intensities of zero-phonon single and double transitions in the multipole-induced spectrum of solid hydrogen

Abstract

The theory of absorption intensities of some zero-phonon single and double transitions in solid H 2 is discussed. General expressions are developed for the integrated absorption coefficients of (i) the single transitions ( v′ = v, J′ = ℓ) ← ( v″ = 0, J″ = 0) in solid para-H 2 and ( v′ = v, J′ = ℓ + 1) ← ( v″ = 0, J″ = 1) in ortho-H 2 interspersed in a matrix of solid para-H 2, and (ii) the double transition [( v′ = v 1, J′ = ℓ) ← ( v″ = 0, J″ = 0)] + S v2←0 (0) in solid para-H 2.
