 Title: INTEGRATED ABSORPTION COEFFICIENT OF GENERAL ZERO-PHONON DOUBLE TRANSITION OF THE TYPE $(\Delta J= \ell)_{v_{1}\leftarrow o}^{\prime} S_{v_{2}}\leftarrow o^{[0]}$ IN SOLID PARA HYDROGEN Creators: Balasubramanian, T. K.; D'Souza, R.; D'Cunha, R.; Rao, K. Narahari Issue Date: 1990 Publisher: Ohio State University Abstract: In continuation of our theoretical $efforts ^{1,2}$ relating to the (induced) infrared spectrum of solid $H_{2}$, we have treated zero-phonon double transitions in which the multipolar induction proceeds via the anisotropic part of the polarizability of $H_{2}$ - This has led us to develop a general formula for the integrated absorption coefficient of a double transition in which one para molecule undergoes the rovibrational transition $(v^{\prime}=v_{1},3^{\prime} =\ell) - (v- = 0,3-=0)$ and another para molecule the $S(\Delta J=2)$ transition $S_{v_{2} \leftarrow o}^{(0)}$, following the absorption of a photon. Using this we could estimate the absorption intensities of some W.S type double transitions in solid para $H_{2}$. Details of the theory will be discussed Description: $^{1}$ T.K. Balasubramanian. R.
