Abstract: | Infrared and microwave spectral measurements are given for three isotopically enriched species of carbonyl selenide. The high-resolution infrared measurements (made near 2000 and 2600 cm?1) provide constants for the following transitions: 10000000 for 16O12C80Se; 10000000 and 11100110 for 18O12C80Se; and 10000000, 11100110, 10010001, and 10010000 for 16O13C80Se. Microwave measurements are given for the J = 4 ← 3, and 3 ← 2 transitions of 18O12C80Se and 16O13C80Se in the 0000, 0110, 0200, 0220, and 0001 states. Equilibrium rotational constants are given for all three isotopic species and the equilibrium bond distances are determined to be and . |
