Level-crossing mechanism

Let us now turn to molecules. In 1966 Zare [399] was the first to treat in detail the problem of applying magnetic level crossing to molecular objects. He used both the classical and quantum mechanical approachs. Three years later he and his collaborators obtained the first experimental results on the Hanle effect with Na2(H1nu) [290], OH(A2 +) [165]. Among the works performed through 1969-1970 one may mention the... 

This is the main reason why a new type of CIDEP is produced through the radical triplet pair mechanism (RTPM). Many variations of CIDEP due to the RTPM have been observed. For example, net absorptive CIDEP was observed in the T-D quenching for positive J values [10]. Here, the level-crossings between IG3/2) - -D-i/2) Q n)produce such... 

Other aldehydes and related compounds have been reacted either alone or catalyzed with sulfuric acid, zinc chloride, magnesium chloride, ammonium chloride, or diammonium phosphate (94). Compounds such as l,3-bis(hydroxymethyl)-2-imidazolidone, glycol acetate, acrolein, chloroacetaldehyde, heptaldehyde, o- and p-chloro-benzaldehydes, furfural, p-hydroxybenzaldehyde, and m-nitrobenz-aldehyde all achieve the ASE by a bulking mechanism and not by low-level cross-linking. At weight gains of 15-25%, the highest ASE reported is 40%.
