The Spectrum of CuO: Rotational Analysis of a Band at 4182 Å

Abstract

A band of the emission spectrum of CuO located at 4182 Å is rotationally analyzed. It is the 0-0 band of the M2Π3/2-X2Π3/2 system. Some perturbations are studied. Molecular constants of the upper state are given.

Theoretical spectroscopy of copper monoxide

“…After the ground state was correctly assigned as a 21-I state [8], a large number of further experimental studies were published [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. They yielded insight into parts of a very complicated spectrum, due to a large number of close-lying electronic states.…”

Laser ablation of YBa_{2}Cu_{3}O_{7-δ} as probed by laser-induced fluorescence spectroscopy

“…In its most common form, tunable dye-laser pulses excite a specific transition of specific species, and emission from this excitedstate population is monitored. As an example, to monitor the presence of CuO, the M 2 ri3/2 *-X 2 n 3 /2 transition at 418.2 nm [24] was pumped and fluorescence to the ground state was monitored. This transition was chosen since it is a relatively strong transition and provides a band with relatively few rotational branches (one P and one R branch), limiting the complexity of the rotational structure that occurs due to the two major isotopes of copper.…”
