In this paper, remote sensing FTIR spectroscopy was used to study the combustion characteristics of infrared pharmaceuticals. At a resolution of 4 cm-1, spectra from 470 0 to 740 cm-1 were collected. From the spectrum intensity distribution of molecular vibrational base-band fine structure emitted from combustion products such as HF, the combustion temperature can be remotely sensed and the change of combustion temperature with time has been given. The experimental results show that the temperature gradient near the combustion surface is very large, There is a sharp change in the temperature field. At the same time, it is also demonstrated that continuous and real-time remote sensing measurement of the flame temperature in the intense and unsteady state of rapid combustion by using FTIR spectroscopy is a fast, accurate and sensitive temperature measurement method without disturbing the flame temperature field , Shows its application prospects in the measurement of combustion temperature, product concentration test and combustion mechanism
