A Diode Laser-Grating Study of the v2 + v5 Band of C2D2
نویسندگان
چکیده
The region of the v2 + v5 band of deuterated acetylene C2D 2 around 2305 cm-1 has been studied using a diode laser-grating spectrometer. The grating spectrum covered the whole range of the band. The structure of the Q branch as well as the Q branches of the hot bands v2 + 2v5 <-v5 and v2 + v4 + v5«v4 together with some special parts have been investigated with the diode laser, too. Molecular constants for the v2 + v5 band with small improvements in the ground state constants are presented. The hot bands were analyzed by taking the /-resonances into account.

Background and Aim: Bacterial disinfection is considered as the primary etiology of pulpal and periapical lesions and as the result, adequate elimination of such infections is one of the purposes of root canal treatment; But since this purpose is impossible to achieve, reducing the bacterial load seems to be as a rational goal. Diode lasers have made their way into endodontics for better disinf...
