The recombination spectra of He I in nebular conditions can be calculated by means of a capture-collision-cascade model based on Brocklehurst's (1972) method when the calculations of the 2(3)P-2(3)S series are corrected. Results are discussed for calculations which include temperatures from 312.5-20,000 K and electron densities of up to 10 to the 6th/cu cm. Line emissions from He I in the optical and IR bands can be interpreted by means of the calculations of recombination spectra.
