what does it read?

• absorption of photon
• spector → specter of photon
• metry = measure

how is it important?

overview

we measure the intneraction of molecules with electromagnetiic radiiation

we’re interested in macromolecules

• the range of wavelengths for light

  • starting from infrared alll the way to ultraviolet depending onthe wavelength

• most of what we use falls under UV (related to DNA) + protein detection

• visible

• IR → wedont usually use it; not many applications
