We have measured the third harmonic generation spectra of epitaxial chloro-indium phthalocyanine (ClInPc) thin films. The χ(3) spectrum in the wavelength range of 970-1650 nm reveals resonance features of ClInPc. Theoretical analysis of the third-order nonlinear optical channels in phthalocyanine allows the assignment of the observed resonances to three- and two-photon resonances of χ(3).
