## Abstract The results of an experimental investigation of the twofold degenerate vibrations in calcite (__E__~__g__~βtype; phonon frequency Ξ©~__E__~/2Ο__c__ = 721 cm^β1^) by means of active spectroscopy method, including a new modification of this method are reported. Beating of a biharmonic pump
## Synopsis We have studied the absorption bands of oxy-and carbonmonoxyhemoglobin in the wavelength range of 650-350 nm (visible and Soret bands) and in the temperature range of 300-20 K. The spectra in the whole temperature range have been successfully deconvoluted in terms of gaussian component
