Adsorption kinetics and absolute coverages

Rates of adsorption are most conveniently expressed as the sticking probability, s, defined by 

As will be discussed in Sect. 3 of this review, numerous values of s and N have been reported using a wide variety of techniques. The reliability of these techniques varies considerably and the following is intended as a critical appraisal to provide a guide for the treatment of the available data and for the intending experimentalist.
