Laser Induced Selective Alignment of Water Spin Isomers
arXiv:0809.4626 · doi:10.1103/PhysRevA.78.063416
Abstract
We consider laser alignment of ortho and para spin isomers of water molecules by using strong and short off-resonance laser pulses. A single pulse is found to create a distinct transient alignment and antialignment of the isomeric species. We suggest selective alignment of one isomeric species (leaving the other species randomly aligned) by a pair of two laser pulses.
