A mass spectrometric study of the photoionization of CS provides 11.319+/-0.006 eV for the ionization potential, in agreement with literature values. Three Rydberg series converging to the C(2)Σ(+) state of the molecular ion are identified. Their limit is 18.003+/-0.006 eV. The threshold for dissociative ionization of CS towards S(+) is located at 70.05+/-0.1 nm and yields D(0)(CS, 0 K)= 709.4 +/- 2.5 kJ/mol. This result is briefly compared with prior data. D(0)(CS, 0 K)=709.6+/-1.2 kJ/mol and D(0)(CS(+), 0 K)=617.1+/-1.3 kJ/mol are selected as the best estimatesfor these quantities.
