Abstract

In this project, ab initio calculations of the spectra of short-lived radioactive water vapor isotopologues H215O, H214O and H219O in the visible, IR and microwave ranges will be carried out. This will guide the determination of promising ranges for the detection of these molecules in the infrared and microwave range for atmospheric and laboratory studies. (AU)
