Description Selective Control of HOD photodissociation has been investigated using simple field profiles. Initial results indicate that preferential dissociation of O–H bond may be achieved from the ground vibrational state and that the O–D bond can be selectively dissociated using only the fundamental excitation in this mode. Dissociation from 2 quanta of excitation in the O–D mode produces 82.8% products with O–D bond dissociation. Preferential maximization of O–D dissociation vis-à-vis O–H bond may also be achieved from the ground vibrational state using a combination of two lasers with carrier frequencies 54920 cm−1 and 52203 cm−1. The use of Field Optimized Initial STate (FOIST) based scheme to enhance selective control of HOD photodissociation provides additional 6 − 8% H–O + D products compared to those obtained without FOIST.
