Abstract

A new experimental technique is presented for the observation of high-resolution hyperfine spectra in real space. The method is demonstrated for the case of the hyperfine spectrum of a single rotational line of iodine. Light from a single-mode ring dye laser, which intersects a supersonic molecular jet, excites only those velocity groups for which one of the hyperfine components is properly Doppler shifted into resonance. This new method is useful for spectral measurement and for the characterization of molecular beams.
