Abstract

We report for the first time highly precise differential microwave spectroscopy, carried out in a cavity-enhanced buffer gas cell. We report a statistically limited differential measurement of $0.08 \pm 0.72$ Hz between (R)- and (S)-1,2-propanediol at frequencies around 15 GHz \footnote{Symmetry 2022, 14(1), 28; https://doi.org/10.3390/sym14010028}. This highly repeatable measurement opens new avenues in studying molecular structure at the $10^{-10}$ level. We also report the coupling of a neon buffer gas beam to this cavity, reaching linewidths of 3 kHz in methyltrioxorhenium, and future modifications to reach 1.5 kHz linewidth.
