Angle‐resolved UV photoelectron spectra were measured for thin films of chloroaluminum phthalocyanine deposited on cleaved MoS 2 surfaces. The take‐off angle (θ) dependence of the photoelectron intensity of the highest π band showed a remarkable sharpening upon cooling the film, indicating that thermal excitation of molecular vibrations gives a considerable broadening of the photoelectron angular distribution. The θ dependence observed at ∼120 K agrees well with that calculated.
