Optimum wavenumber regions were observed at 200-400 and 630-730 cm-1 for HCTZ, and 980-1100 cm-1 for RMP using principal component analysis. Partial least squares (PLS) regression was performed to establish the predictive calibration models. The PLS developed models showed excellent linearity (R2 = 0.986 and 0.974), selectivity (PC1 = 98.6% and 91.9%) and accuracy (RMSEcv = 1.586 and 0.645%) for HCTZ and RMP, respectively. Additionally, RMSEP values were reported as 1.237 and 1.007% for HCTZ and RMP, respectively, depic
