Br 2. The isotopic effect was observed in a spectrum of both HCl and DCl with DCl at a lower wavenumber than HCl which coincided with 37 Cl being observed at a lower frequency than 35 Cl.

The fundamental transitions, v=±1, are the most commonly occurring, and the probability of overtones rapid decreases as \( \Delta v > \pm 1\) gets bigger.

If you need an account, please register here, Velocity-map ion imaging has been used to study the vibrational predissociation dynamics of the HCl dimer following infrared (IR) excitation in the HCl stretch overtone region near 1.77 Å. HCl monomer predissociation products were detected state-selectively using 2 + 1 resonance-enhanced multiphoton ionization spectroscopy. Add annotation to spectrum. Cl 2.
