Strong-field induced bond rearrangement in triatomic molecules
Abstract
A comparative study of strong-field induced bond rearrangement is carried out for three triatomic molecules: carbon dioxide (CO2), carbonyl sulfide (OCS), and water (D2O). Specifically, we use COLTRIMS to measure the branching ratio for the formation of AC+ from ABC2+ following double ionization by intense, short (23 fs, 790 nm) laser pulses. Our study shows that the branching ratio of D2O2+ -> D2++ O+ is higher than that of CO22+ -> O2++ C+, which in turn is higher than that of OCS2+ -> SO+ + C+, although all three values are within an order of magnitude of each other. Additionally, we examined the isotopic and linear-chirp dependencies of bond rearrangement in water.
