Spectra were recorded at 4 cm−1 resolution using a Bruker IFS66 interferometer coupled to a Bruker FRA106 Raman module equipped with a continuous Nd: Yag laser providing excitation at 1,064 nm. All spectra were recorded at room temperature with backscattering geometry from samples in hermetically closed glass capillaries. The spectra resulted from 500 to 5,000 cm−1.

Molecules 1b and 2b were obtained by means of the alkaline hydrolysis of 2-(4-chlorophenyl)-5-(pyrrolidin-1-yl)-2H-1,2,3-triazole-4-carbonitrile according to previously developed procedures [17 (link),21 (link)]. 1,2,3-triazole-containing molecules form a white powder at room temperature. The IR spectra were recorded in powder form at the spectral range of 400–4000 cm–1 on a Brüker IFS-66 FTIR spectrometer equipped with a Globar source, a Ge/KBr beam splitter and a TGS detector. For spectrum acquisition, 50 interferograms were collected. The Raman spectrum was recorded in the 50–4000 cm−1 range on a Brüker (Billerica, MA, USA) IFS 66 optical bench with a FRA106 Raman module connected to a microcomputer. The sample was mounted in the sample illuminator using an optical mount without sample pre-treatment of any type. A Nd:YAG laser at 1064 nm was used as an excitation source. The laser power was set at 250 mW and the spectrum was recorded over 1000 scans at room temperature.

The fine sample 2C5FP was procured from Lancaster chemical company, UK. The FT-IR spectrum was recorded in BRUKER IFS 66V spectrometer and FT-Raman spectrum was recorded using FRA-106 Raman module equipped with Nd: YAG Laser source operating at 1.064μm width with 200mW power. Both FT-IR and FT-Raman spectra were measured in the region of 4000–100cm−1 and 3500-100cm−1, respectively. The spectral wave numbers of all bands are accurate to ± cm−1. The carbon and proton (13C & 1H) NMR spectra were recorded in Acetone using TMS as an internal standard on Bruker NMR spectrometer at 400 MHz. The spectral measurements were recorded at IIT (SAIF), Chennai, India.

Triazoles 1a and 2a were obtained by alkaline hydrolysis of 2-(4-methoxyphenyl)-5-(pyrrolidin-1-yl)-2H-1,2,3-triazole-4-carbonitrile according to previously developed procedures [24 (link),25 (link)]. The IR spectra in the powder form were recorded in the 400–4000 cm–1 range on a Brüker IFS-66 FTIR spectrometer equipped with a Globar source, Ge/KBr beam splitter and a TGS detector. For the spectrum acquisition, 50 interferograms were collected. The Raman spectrum was registered in the 50–4000 cm−1 range on a Brüker IFS 66 optical bench with an FRA106 Raman module attachment interfaced to a microcomputer. The sample was mounted in the sample illuminator using an optical mount without sample pre-treatment. A Nd:YAG laser at 1064 nm was utilized as the exciting source. The laser power was set at 250 mW and the spectrum was recorded over 1000 scans at room temperature.

FT-Raman spectra of samples were recorded with a Bruker IFS66 optics system using a Bruker FRA 106 Raman module. The excitation source was an Nd: YAG laser operating at 1064 nm and a laser power of 50 mW was used. The FT-Raman module was equipped with a liquid nitrogen-cooled germanium diode detector with an extended spectrum band width covering the wave number range 1800-450 cm -1 . Samples were placed in stainless steel sample cups and scanned 200 times with the resolution set at 8 cm -1 . The observed band wave numbers were calibrated against the internal laser frequency and are correct to better than ±1 cm -1 . The spectra were corrected for instrument response. The experiments were run at a controlled room temperature of 20±1°C.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
