Mass Spectrometry
This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is als…

Chapter 20, Problem 20.24P

Pyridine exhibits a UV transition of the type n → π * at 270 nm. In this transition, one of the unshared electrons on nitrogen is promoted from a nonbonding MO to a π* (antibonding) MO. What is the effect on this UV peak if pyridine is protonated?
