Abstract

In this work, we report the studies of air molecules by recently developed reflection interferometer. The interferometer is highly sensitive so that the interference signal allows the monitoring of the index of the refraction of air under various vacuum, revealing the molecular behavior of air molecules by Kramers–Kronig relations. The interferometer is composed of a channel of a thickness of 13 µm and a width of 5mm. We have used a green laser of wavelength 532 nm and a red laser of wavelength 633 nm with the incident beam at an oblique angle. The vacuum ranged from 0 to -9.2 PSI. Our results reveal the molecular details of the dynamic nature of air molecules.
