Abstract
A description is given of a molecular beam apparatus which extends high resolution absorption spectroscopy into the shorter millimeter wavelength region (up to 500 GHz). A parallel‐plate‐type absorption cell, allowing for Stark modulation, is used with the molecular beam passing between the plates. The half‐width of the absorption lines is about 5 kHz at a resonance frequency of about 200 GHz.Keywords
