Only certain electron transitions are allowed from one energy level to another. In one-electron species, the change in the quantum number I of an allowed transition must be ±1. For example, a 3p electron can drop directly to a 2s orbital but not to a 2p. Thus, in the UV series, where ninal = 1, allowed electron transitions can start in a p orbital (I = 1) ofn= 2 or higher, not in an s (I = 0) or d (l = 2) orbital of n = 2 or higher.
