摘要：

Systematic analysis of the temperature dependence of the intensity ratio between already assigned and unassigned transitions enabled the determination of the most probable energy of the lower state of the unassigned transition. Such a procedure has been applied to transitions of (NH3)-N-14 ammonia in the range 6626-6805 cm(-1) between 130 and 300 K. This information is of great interest in the considerable task of the assignment of the complete 1.5 mu m infrared spectral range where combination and overtone vibrational bands are present. 2451 transitions have been observed at different temperatures. For 2133 the line strength and for 1956 transitions the values of lower state energies were derived. Our work was compared with recent Fourier transform study covering a larger energy range (6300-7000 cm(-1)) with smaller temperature range (185-296 K)
