If your cold emails do not match these standards then yes, you’ve got to go back and revise them. Yes, that’s a pain, but at least you’ll know what to do the next time around. 1 IR-Spectroscopy IR region The part of electromagnetic radiation between the visible and microwave regions 0.8  m to 50  m ( 12,500 cm -1 - 200 cm -1 ) is called IR region Most interested region in Infrared Spectroscopy is between 2.5
