New values of the solar photospheric abundances of titanium, chromium and nickel have been derived from a study of weak infrared transitions of Ti I, Cr I and Ni I for which theoretical oscillator strengths are available (Kurucz and Peytremann, 1975). The solar abundances were obtained by a previously described method (Biemont et al., 1975) using the Harvard Smithsonian Reference Atmosphere (HSRA) and assuming weak turbulence. The effects of the model on the abundances were assessed and found to be insignificant for the lines studied. The calculated solar abundances for Ti I (4.82), Cr I (5.69) and Ni I (6.21) are in good agreement with meteoritic and coronal values.
