Spectroscopy of the E state of iodine monofluoride and rotational energy transfer of the B state in collisions with He, using two-photon sequential absorption spectroscopy
… (TPSA) technique has been used to investigate a state of 0<sup>+</sup> symmetry of IF (iodine monofluoride) which has T<sub>e</sub>= 41292 cm<sup>-1</sup>, ω<sub>e</sub> = 248.8 cm<sup>-1</sup>, and B<sub>e</sub> = .1292 cm<sup>-1</sup>. This state has been designated the E state and dissociates …
