Abstract
In the fourth positive system, A 1Π←X 1Σ+, of CO, electric quadrupole transitions (ΔJ=2) have been observed for the first time in bands of an electric dipole allowed transition. This system also represents the first example of an electric quadrupole transition to be observed in a heteronuclear diatomic molecule. The quadrupole transition probability has been determined to be ≈1.1×103 sec−1. This value compares well with the value of ≈2.0×103 sec−1 determined for the quadrupole transition probability of the electric dipole forbidden a1 Πg←X 1Σg+ transition in the isoelectronic N2 molecule.
