✦ Synopsis


Various Ti-based oxides were used as far-infrared (FIR) radiation sources. The temperature increases and emissivities of aluminum panels coated with these oxides were measured. To explain their different FIR emissivities, the electronic energy levels of these oxides were calculated using the direct-variational Xa molecular orbital method. Ti 2 O 3 and TiO were found to be more effective materials as FIR sources than was TiO 2 in the wavelength range 3-7 lm. The wide band gap of TiO 2 is the cause of its relatively low emissivity.

High-resolution Fourier transform spectra of LiH and LiD were recorded in the far-infrared region, 100 -360 cm 01 , and the mid-infrared regions, 800 -1200 cm 01 and 2000 -3000 cm 01 . A total of 261 pure rotational lines and 678 rovibrational lines were measured for the isotopomers 6 LiH (D) and 7
