Reviewer 2 Report

This work is interesting. The manuscript is prepared well. The design and strategy of the work are also good and important. I suggest this manuscript will be accepted for publication with a minor correction after including the below comments. The introduction of the manuscript should be revised to include the important of the work. Why the air effect is important on methane properties, etc. The language and punctuation of the manuscript should be improved. The complete terms of all abbreviations should be included before their first use.

Author Response

1. The introduction of the manuscript should be revised to include the important of the work. Why the air effect is important on methane properties, etc.

 - The introduction has been improved. We have added this information to the text:

 “Pressure and different molecular environment significantly affect the spectroscopic characteristics of the ν₁ band of CH₄ [22–30]. The higher the molar fraction of the perturbing component, the stronger its influence on the spectrum. The effect of the main components of air cannot be neglected since their concentration is orders of magnitude higher than CH₄. Thus, it is necessary to account for the changes in the CH₄ spectrum to improve the accuracy of measurements of its content from the Raman spectra of air.”

 

2. Moderate English changes required. The language and punctuation of the manuscript should be improved.

 - We did it. The language and punctuation were improved.

 

3. The complete terms of all abbreviations should be included before their first use.

 - We included complete terms of all abbreviations wherever necessary.
