YIP - Ultrasensitive Infrared Spectroscopy of Molecular Ions of Importance in Atmospheric Chemistry and Propulsion. Final Report February 1, 2007-May 31, 2010

摘要

The objective of this effort has been to develop a novel instrument for the spectroscopic study of molecular ions, which we call SCRIBES (Sensitive, Cooled, Resolved, Ion BEam Spectroscopy). The instrument has been constructed during the period of this award, and ultrasensitive spectroscopic techniques (including NICE-OHMS) have been employed in an effort to obtain an absorption spectrum of the N2+ molecular ion. While the SCRIBES instrument is still being commissioned, this work has already led to the development of an unexpected and exciting approach for molecular ion spectroscopy: cavity-enhanced velocity modulation spectroscopy.
