elements and formulae

Provides properties for the elements in the periodic table, and functions for parsing formulae and calculating isotope distributions.

Calculations are based on the isotopic composition of the elements. Mass deficiency due to chemical bonding is not taken into account.

Examples of valid formulae are H2O, [2H]2O, CH3COOH, EtOH, CuSO4.5H2O, and (COOH)2. Formulae are case sensitive.
