The technique of optical–optical double-resonance (OODR) spectroscopy has been used to study the collisional dynamics of the ƒ(0+g) state of I2 in the presence of Xe. Using the B(3Π0+u) state as an intermediate we have succeeded in selectively populating specific rovibronic levels of the ƒ(0+g) state from v′= 0 up to v′= 107. Dispersed fluorescence has been observed from a number of single rovibronic levels in this range. The energetic threshold for the chemiluminescent reaction I2(ƒ 0+g, v′=n)+ Xe → XeI(B2Σ1/2)+ I(2P3/2) has been determined as 52 460 ± 400 cm–1, which corresponds to v′= 52–57. The reaction was monitored by observing fluorescence from XeI(B2Σ1/2) at 253 nm.
