Adalbert Farkas, Orthohydrogen, Parahydrogen, and Heavy Hydrogen (1935), is a classic monograph by an early researcher in this area. Isidor Kirshenbaum, Physical Properties and Analysis of Heavy Water (1951), is a comprehensive treatise. Willard F. Libby, Collected Papers, vol. 1, Tritium and Radiocarbon (1981), contains classic articles on tritium dating. E. Anthony Evans, Tritium and Its Compounds, 2nd ed. (1974), is a compact source of information. R.P. Bell, The Proton in Chemistry, 2nd ed. (1973); and Howard K. Rae (ed.), Separation of Hydrogen Isotopes (1978), are also useful.
