Abstract
The technique of mass selective pulsed field threshold ionization of h igh long-lived Rydberg states has been applied to dibenzo-p-dioxin (DD ), DD . Ar, and DD-Kr-84 yielding adiabatic ionization energies of 612 83, 61071, and 61005 cm(-1) respectively. A sharp energetic threshold for the disappearance of the parent threshold ion signal of (DD . Ar)( +) and the appearance of the daughter threshold ion signal is observed . This leads to accurate values of the dissociation energy E(0) = 717 cm(-1) in (DD . Ar)(+), E(0) = 918 cm(-1) in (DD .Kr-84)(+) and to D-0 = 505 cm(-1) in DD . Ar, D-0 = 640 cm(-1) in DD .Kr-84.
