The kinetics and activation energy for electron solvation in 1-propano
l and 2-propanol were measured from -20 to -50 degrees C. The activati
on energy for electron solvation in 1-propanol (14.4 +/- 1.4 kJ/mol) i
s less than that for hydrogen-bond breakage while the activation energ
y for electron solvation in 2-propanol (21 +/- 2 kJ/mol) is greater th
an that for hydrogen-bond breakage. These results suggest that (1) the
electron is solvated in preexisting clusters, (2) in 1-propanol, thes
e clusters are cyclic and rotational motion that breaks hydrogen bonds
is not rate-limiting, and (3) in 2-propanol, linear structures domina
te and the solvation process requires hydrogen-bond breakage.
