Enhancement of the degree of control of photofragment distributions by laser phase modulation

2020-01-16T12:54:28+01:00Tags: , , , , |

Authors: Garcia-Vela, A. Contribution: Article Journal: INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY Publication date: 2019/02/15 DOI: 10.1002/qua.25813 Abstract: The possibility of enhancing the degree of control of a transient photofragment distribution achieved by means of laser phase modulation is explored. Such a control is exerted through interference between overlapping resonances, which are populated in a superposition by [...]
