Ft ir 6300 fourier transforminfrared spectrometer

All materials and reagents used in this study were analytical grade obtained from Sigma Aldrich and used as its. The Stuart SMP30 (115/230 VAC, integrated cooling 350 °C to 50 °C in 10 min, United Kingdom) melting point instrument was used to determine the melting points of NSB and NCSB. FTIR spectra of NSB and NCSB were obtained using an FT/IR-6300 Fourier Transform Infrared Spectrometer (Jasco, Japan). A Bruker NMR instrument was used to record 1 H NMR spectra at 400 MHz of NSB and NCSB.
The NCSB sensor's mass spectra were recorded using an LC-MS Spectrometer Model Q-ToF Micro Waters. The fluorescence experiments were carried out on a Jasco FP-6500 spectrometer with a quartz cuvette recorded at 400 MHz using a Bruker NMR instrument. The Mass spectra of the surfactant were recorded on MS Spectrometer Model Q-ToF Micro Waters. The fluorescence experiments were performed on an FP-6500 spectrofluorometer (Jasco, Japan) using a quartz cuvette with a 1-cm path length. The absorption spectra were obtained using an Agilent 8543 (Agilent, USA) UV/Vis spectrophotometer.
