Spectrum two uatr ftir spectrometer

Infrared spectra were recorded using a Spectrum Two UATR FTIR spectrometer (Perkin Elmer Inc., Waltham, MA, USA) equipped with a diamond ATR (attenuated total reflection) window. All spectra were recorded in the spectral range of 400–4000 cm⁻¹ with 12 scans at a spectral resolution of 4 cm⁻¹. Before each measurement, the diamond ATR crystal was cleaned with isopropanol.

ATR-FTIR spectra of AzA, CC, MA, and DES MCP116 (both with and without the presence of the drug), were carried out using (Perkin Elmer Spectrum Two UATR FT-IR spectrometer, Waltham, MA, USA). Scan resolution was set to 4 cm⁻¹, with 32 samples per scan. Spectra were acquired over a range of 4000–450 cm⁻¹.

The proton nuclear magnetic resonance (¹H NMR) spectra were recorded on a Brucker 300 Mhz NMR spectrometer using tetramethylsilane (TMS) as internal reference. Chemical shifts are reported as δ in parts per million (ppm). The samples were prepared by dissolving 5 mg of each form in 600 μl of CDCl₃.
FTIR spectra were run on a Perkin-Elmer Spectrum Two UATR FT-IR spectrometer. The samples were applied as solids.
Thermal characteristic was carried out on a Mettler Toledo DCS 25 measuring cell with TC15 TA Controller, calibrated with indium to ensure the accuracy of the calorimetric scale. Samples weighing 3 mg were characterized in sealed 40 μL aluminium pans and subjected to thermal analysis under a flowing argon atmosphere (30 cm³ min⁻¹), using heating rate of 5 °C min⁻¹.
Elemental analyses for carbon, nitrogen and hydrogen were carried out on an Carlo Erba NA 1500 analyser and were within ± 0.4 % of the theoretical value.
