The adiabatic ionization energies of two spin states are found to be 82 257 ± 5 and 84 823 ± 5 cm 1, respectively. The two-photon MATI spectrum exhibits an extensive vibrational structure. The active modes, i
1. A liquid compound gave a mass spectrum showing a strong molecular ion at m/z = 156. The only fragment ions are seen at m/z = 127 and 29. Suggest a structure of this compound. 2. A liquid compound gave a mass spectrum in which the molecular ion appears as a pair of equal inte...

The base peak at 43 is bromine in an outright cleavage from the propyl chain. My problem comes from identifying how the peaks at 27 and 41 come about (they are relatively abundant, slightly larger then the parent ion, about 25-30%ish judging from the spectrum) My first thought is a HBr...
1PRACTICE PROBLEM Draw the1H NMR spectrum of the following molecule making sure to show the integration of each peak, without thinking about the relative placement of the signals (i.e., the chemical shift) or the splitting patterns. Label each signal according to the set of equivalen...
