Intrinsic Calibration of Molecular Alignment Using Rotational Echoes
arXiv:1912.13095 · doi:10.1103/PhysRevResearch.2.023351
Abstract
We propose and experimentally validate the use of rotational echo responses for obtaining the degree of molecular alignment induced in a gas. The method is independent of various parameters that are hardly accessible in most experimental configurations such as the effective length of interaction and the gas density as it relies on the intrinsic, self-contained dynamics of the rotational echo response.
