Fox, Kenneth; Turner, J. E. published an article in 1966, the title of the article was W.K.B. treatment of bound states in an electric-dipole potential.Safety of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile And the article contains the following content:
The W.K.B. (Wentzel-Kramers-Brillouin) method is applied to the problem of bound states of an electron in the field of a finite dipole. A necessary condition for binding is derived which suggests that bound states may exist only if the dipole moment is larger than a certain min. value. The number of bound states given by the W.K.B. method is comparable to the exact number for the 1- and 3-dimensional sq.-well potentials. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Safety of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile
2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas:2510-01-2) belongs to nitriles. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Safety of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile
