Abstract.

We have solved the time dependent Schrodinger equation by using the Chebyshev polynomial scheme and Fourier grid Hamiltonian method to calculate the dissociation cross section of NaH molecule by 1-photon absorption from the X¹ S⁺ state to the B¹P state. We have found that the results differ significantly from an earlier calculation [1] although we have used the same set of potential energy curves [2].

Keywords:  Photodissociation; molecules; interaction of  photon with molecules.
