The first negative (B2Σ+→X2Σ+) system of CO+: excitation of higher vibrational levels

The 1-v″ bands progression of the B2Σ+→X2Σ+ system of 12C17O+

“…Carbon has three natural isotopes ( 12 C, 13 C and 14 C), together with three isotopes of oxygen ( 16 O, 17 O and 18 O) nine different isotopomers of CO + can be anticipated. Using experimental data from this work and from previous studies [14,17,34], the reduced mass dependence of the c e constants for the four isotope species, have been graphically presented in Fig.…”

“…In the laboratory B 2 R + fi X 2 R + of CO + has been extensively studied for many years beginning with Jevons [5] in 1924. From this time many measurements have been made on 12 C 16 O + [6][7][8][9][10][11][12][13][14] and other isotopic species: 13 C 16 O + [12,[15][16][17], 12 C 18 O + [18][19][20] and 13 C 18 O + [21,22]. There has been only one previous observation of the B fi X system in emission spectrum of CO + with the 17 O isotope, which natural abundance is about 0.04%.…”
