Asymmetrical splitting

Figure 3. Asymmetrical splitting (mass spectrometry) of the tetra-TMSi derivative of 4,4 -dihydroxytruxinic acid.

Here v, vo pertain to the vibrational levels of the lu, 0 states, respectively. It can easily be seen from (5.49), (5.50) and (5.51) that the condition of asymmetric splitting of M-levels (5.42) is satisfied, since... 

Scheme 8.1 Symmetric and asymmetric splitting of diborane by ammonia.

The use of simultaneous FTIR/MS using stream splitting to the parallel detectors was reported by Wilkins for petrochemical samples in an MDGC system. Asymmetric splitting was necessary because of the different sensitivities of the detection methods -most of the flow is diverted to the FTIR channel. 

It has been shown that the hydrogen desorption reaction is reversible and the end products lithium hydride and boron absorb hydrogen at 690 °C and 200 bar to form LiBH4 [37], Also the reaction of the elemental hydride with diborane forms the tetrahydroboride, and the reaction proceeds via an asymmetric splitting of the diborane due to the overlap of the molecular orbitals of diborane with the orbitals from the H at the surface of the elemental hydride. The diborane splits into an BHLi and a BH3, formed with the hydrogen from the elemental hydride [38].
