Abstract

A near infrared spectrometer based on the self-scanning Tm-doped fiber laser is developed. The spectrometer is applied to measurements of the water nuclear spin isomer abundances using water absorption lines in the vibrational band ν 2+ν3 near 1.91 µm. The ortho/para ratio of water nuclear spin isomers is measured to be equal to 3.06 ± 0.02, which is close to the theoretical prediction of 3 at room temperature.
