Emission and absorption spectra of the HgZn excimer

Extensive and previously unknown fluorescence and excitation spectra of the HgZn excimer have been observed and correlated with a potential energy (PE) diagram. The spectra were excited in a HgZn mixture contained in a quartz vapor cell by successive pulses from two dye lasers using pump‐and‐probe methods. A vibrational analysis of the spectra yield the frequencies and anharmonicities for the states involved in the absorption and emission processes.
