چکیده | ||
The cooling of molecules during the adiabatic expansion of supersonic seeded molecular beams is reviewed and illustrated by the example of NO -molecules. The reduction of the Doppler width by collimation of the beam and the cooling to low rotational temperatures brings a significant simplification of the complex NO -absorption spectrum and allows its assignment. The measured rotational temperature is T = 10°K. Some examples from our work illustrate this promising technique of high resolution laser spectroscopy in cold beams | ||
