Non-persistent

Flowever, it also necessitates a strictly constant ratio of field to frequency, over the duration of the experiment. Although the master frequency source can be held very constant by a thennostatted source, the field is always vulnerable to local movements of metal, and to any non-persistence of the magnet current. Therefore the field is locked to the frequency tlirough a feedback loop that uses continuous, background...

Vapor Density The ratio of the density of any gas or vapor to the density of air, under the same conditions of temperature and pressure that is, a measure of how heavy the vapor is in relation to the same volume of air. Air is considered to have a molecular weight of 1. As an example, the higher the vapor density is in relation to 1.0, the longer it will persist in low-lying areas such as valleys, trenches, and cellar holes. If the vapor pressure is less than 1, a chemical agent would will likely be non-persistent and dissipate quickly into the atmosphere. 

A few hints about methods of generation of non-persistent aminoxyl radicals, which will be quoted a few times later in the chapter, are now given. The dichotomy of generation of an aminoxyl radical from the parent hydroxylamine has already been outlined in Scheme 2.
