Experimental data on carbon nanotube carpet and synthetic opals have been
 compared by visible, infrared spectroscopy, and electron microscopy. Spectral features of
 the objects under study in infrared region are registered. Three regions of abnormal
 behavior of reflectance and absorbance for carbon nanotube carpet and two regions for
 opals in the 7000-2000 cm⁻¹ are observed in comparison with the separated nanotubes or
 SiO₂ globules in disordered states and/or condensed state. The spectroscopic features of
 the photonic crystals caused by their different microstructures at different length scales
 and basis for development of a proper model for light propagation through the photonic
 crystals in the IR region are presented for discussion.
