A high-accuracy computed water line list

A computed list of H 2 16 O infrared transition frequencies and intensities is presented. The list, BT2, was produced using a discrete variable representation two-step approach for solving the rotation-vibration nuclear motions. It is the most complete water line list in existence, comprising over 500 million transitions (65 per cent more than any other list) and it is also the most accurate (over 90 per cent of all known experimental energy levels are within 0.3 cm -1 of the BT2 values). Its accuracy has been confirmed by extensive testing against astronomical and laboratory data.
