Use a group theoretical argument to decide which of the following transitions are electric-dipole allowed: (a) the π* ← π transition in ethene, (b) the π* ← n transition in a carbonyl group in a C2v environment.

A series of lines in the spectrum of neutral Li atoms rise from transitions between 1s22p1 2P and 1s2nd1 2D and occur at 610.36 nm, 460.29 nm, and 413.23 nm. The d orbitals are hydrogenic. It is known that the transition from the 2P to the 2S term (which arises from the ground-state configuration 1s22s1) occurs at 670.78 nm. Calculate the ionization energy of the ground-state atom.

2.2 You know that the wavenumbers of the rotational transition J = 1← 0 for 1H35Cl and 2H35Cl are 20.8784 and 10.7840cm-1, respectively.
