Abstract
The photoacoustic calorimetry technique is described in detail, as
a tool for high precision thermochemistry studies of transient species.
The need for a method to assess a photoacoustic calorimeter is underlined,
and the reaction of phenol with di- tert -butyl peroxide is proposed
as a possible candidate. The method for determining the O-H bond
dissociation enthalpy in phenol from the photoacoustic experiments
is discussed and a proposed #direct# method is compared with an #indirect#
method established in the literature. The obtained value of (359.5
��� 5.2)kJ � mol�-�1is in good agreement with the literature result
obtained by the #indirect# method.
