More accurately, we can use the method of combination differences, while still neglecting centrifugal distortion, to obtain B" and B. Transitions having wavenumbers v[5(J — 2)] and v[0 J + 2)] have a common upper state so that the corresponding combination difference A4F(J) is a function of B" only ... 

Increased hardness lowered ductility and impact resistance higher D-B transition temperatures... 

According to these transition state models2,. (y -products are formed via a chair (C) conformation where both the enolate and the imine are in E geometry (E,E) or via a boat (B) transition state where the enolate is in Z and the imine in Econfiguration C(E.E) or B(Z,E). antt-Products are formed via B(E,E) and C(Z,E) transition states. The transition states leading to 1 and 2 are based upon the more stable E geometry of the imine. For cyclic imines a complementary set of transition states can be applied based on the Z geometry of the imine.

In a less polar solvent, 951 ethanol, absorptions at 241 and 286 nm were reported with the A - B transition being obscured by solvent absorption. Also in HFIP, DMT displays a fluorescence approximately 100 times as intense as in ethanol solution was reported. 

Besides the pressure minimum, the 3He melting curve presents a few characteristics which can be used as temperature and pressure reference points the superfluid A transition, the A-B transition in the superfluid and N6el transition in the solid. The reference values are reported in Table 8.7 (see also Section 2.2.4).
