The high-resolution infrared spectrum of DCF3 was investigated in the 2000 cm-1 region, with the aim of assigning and analyzing the overtone bands 2v5 (A1 + E), as well as the combination band v2 + v5 (E). The present paper reports on the first high-resolution study of the v2 = v5 = 1 and v5 = 2 levels, through the analysis of the combination v2 + v5 and the overtone 2ν5∓2 bands respectively. This analysis can be thought of as a necessary step toward the reinvestigation of the complicated vibrational pattern in the CD stretching fundamental region.
