The Raman-active phonons in perovskite-like LaMn1-xCoxO3 (x = 0, 0.2, 0.3,
0.4, and 1.0) were studied by measuring Raman spectra at temperatures of 295
and 5 K. The changes in the spectra with Co doping are correlated with the
decrease of orthorhombic distortions. Surprisingly more phonon lines than
allowed for the rhombohedral LaCoO3 structure were observed in the spectra.
