✦ Synopsis

47,49 Ž . A Ti NMR characterisation is given of various polymorphs of TiO anatase, rutile and brookite , Ti O , perovskites 2 2 3

CaTiO and BaTiO , FeTiO , TiB , titanium metal, the titanium aluminides Ti Al, TiAl, TiAl , TiAl , and TiAg. Values

Ž of chemical or Knight shift, nuclear quadrupole coupling constant and asymmetry parameter were derived from the 1r2, . Ž . y1r2 powder lineshapes. For TiB , titanium metal, TiAl, and TiAl , where " 1r2, 3r2 , and higher satellite transitions 2 3

were observed, a value for the axial component of the Knight shift was obtained.
