The radiative lifetimes for a number of electronic states of the alkaline earth monohalide molecules MX, where M denotes Ca, Sr, or Ba and where X denotes F, Cl, Br, or I, have been determined directly from the rate of fluorescence decay with time using a pulsed dye laser as an excitation source. The measured lifetimes in nanoseconds are CaF: A1 21.9(4.0), A2 18.4(4.1), B 25.1(4.0); CaCl: A1 29.4(1.8), A2 28.4(2.6), B 38.2(3.9), C 25.0(2.1); CaBr: A1 34.2(2.9), A2 33.7(1.9), B 42.9(3.1), C1 33.2(4.0), C2 31.8(3.7); CaI: A1 41.7(2.3), A2 41.6(3.4), B 50.9(1.7); SrF: A1 24.1(2.0), A2 22.6(4.7); SrCl, A1 31.3(2.7), A2 30.4(3.6), B 38.8(2.1), C1 26.1(1.9), C2 26.0(1.6); SrBr: A1 34.3(2.3), A2 33.2(1.6), B 42.2(1.6), C1 30.3(2.6), C2 28.1(1.3); SrI: A1 43.3(1.6), A2 41.9(1.3), B 46.0(2.0), C1 36.0(3.7); BaF: C1 23.8(2.3), C2 23.5(0.7); BaCl: C1 17.5(0.8), C2 16.6(0.6); BaBr: C1 17.9(1.0), C2 16.5(1.4); BaI: C1 17.9(1.9), C2 16.0(1.5), where A1, A2, B, C1, and C2 denote, respectively, the A 2Π1/2, A 2Π3/2, B 2Σ...
