Multiple fragmentation

For lower scaled pressures, velocity can be calculated with the equation proposed by Baum (1987) which produces disintegration of both cylindrical and spherical vessels into multiple fragments (Vj = O.SSoo ). Such a result can also be obtained by use of Figure 6.33. However, actual experience is that ruptures rarely... [Pg.232]

One of the more challenging things to understand in these multiple-fragment models is the evolution of the present-day surviving thin old disk, particularly since a recent accretion of the thick disk could destroy the thin disk. Further, in these models stars should not form in a thin disk at all until after most of the merging is complete, since otherwise disks have too small a scale-length (Navarro Steinmetz 1997). A solution to both these issues may be that the local old thin disk is also accreted in these models. Here the recent results of many authors (cf... [Pg.246]

The reactions of excited ions are not always as straightforward as expected. Of course, the existence of multiple fragmentation pathways for an ion consisting of several tens of atoms brings about different types of reactions all of which certainly will not lead to the same fc(E) function.

Approximately 1,200 amines and 300 carboxylic acids were selected for inclusion in the fragment libraries, from which approximately 20 fragment libraries were synthesized. These libraries yielded 2,000 products with sufficient purity (>95%) and quantity (1.2 mL of 30 xM solution), and the product structures were confirmed via ID NMR. This fragment collection became known as the NMR Combicores to denote their purpose and their combichem origin. It was distributed across several major Pfizer research sites and used in multiple fragment screens. [Pg.225]

When a compound object is created, its structure may have multiple fragments. The system should first decompose the structure into individual fragments and let the chemist specify their roles—parent, salt, and their coefficients. This is done at the Created State, which transitions to the Fragmented State when the fragmentation finishes. Next, the system must make sure the structure is fully compliant with structure conventions. This is tlie structure QC process. There are three possibilities as a result of this process ... [Pg.74]

Whereas the interface produces analyte ions the mass analyser identifies the corresponding masses or may allow fragmentation for tandem-mass spectrometry (MS/MS or MS2) or multiple fragmentation (MS ). Single quadrupole (SQ), triple... [Pg.326]
