Multi-mass velocity-resolved kinetics of surface reactions at 100 kHz acquisition rate Open
Velocity-resolved kinetics (VRK) employs a pulsed molecular beam that initiates reactions at a surface and a pulsed ionization-laser that detects desorbed products, exploiting ion-imaging-based, velocity-sensitive detection to derive the p…
