Abstract
The rotational structure of the fluorescence excitation spectrum of the B (v′=10) ←X (v″=0) transition of the van der Waals molecule HeI2 has been measured and analyzed. The analysis indicates that the molecule has a nonlinear equilibrium structure with R′=4.79±0.22 Å and R″=4.47±0.13 Å, where R is the perpendicular distance from the helium atom to a line drawn through the iodine atoms.
