By me ans of a Rydberg-Ritz fitting procedure accurate quantum defect data and ionizat ion limits are given. The ionization limits are in agreement with the limits der ived from energy data of other l-series which have been measured recently with l aser spectroscopy techniques. The compact Rydberg-Ritz formulas can serve as han dy secondary wavelength standards with high precision. A compilation of the most accurate Rydberg-Ritz coefficient of all alkali term series with l ? 3 is pre sented and the present status of alkali quantum defect data is discussed. This s et of data includes also recent measurements of 133Cs n2S1/2 and n2D3/2,5/2 leve ls and of some low-lying 7Li levels.
