An optical system model for the identification of Carbon-Hydrogen stretching using spectroscopy is demonstrated and applied to the experiment setup. The optical simulation is achieved using simulation software and performed in a two-mirror system. The optical setup covers a wavelength range of 600 nm to 1200 nm which is a new study based on carbon-hydrogen stretch and test with samples from the alkene group. Significant results of the Carbon-Hydrogen stretch from the alkene group at 1149 nm are detected in Dichloromethane and ethanol. This observation is recorded in real-time and applied in a fast diagnostic system. The isosbestic point of water is measured at 970 nm and useful for our system spectral calibration. The result also shows the ability to quantify the chemical bond of a sample based on two peaks of absorption due to the C-H stretching. This gives a better opportunity for Chemometrics to perform accurately.
