It's good question.but you know each program or any software need a data base loading from library or literature to design it. 

Dear Krishna Saini,

of course, software is there. you can calculate IR frequencies theoretically from Gaussian, Gammes, etc. you can assign your peaks either tentatively by visualizing the output file in the respective visualization tools or exactly by finding PED using MOLVIB, GAR2PED, VEDA programs.

best wishes.

thank you for your response Mr. Bilal, but i want to assign the peaks of FTIR for which bonds feature they are coming in FTIR curve?

I will be very grateful if you will help me in this issue. please tell me what should i do now?
