Document Summary
Di erent types of spectroscopy a ord information about molecules and their structure. Spin is ipped to a higher energy state. Difference is chemist nmr is done on high resolution instrument. Just get a concentration gradient because if more water more nuclei can be ipped. Little less energy required to bend a molecule! Intensity of absorption or emission of emr vs frequency or wavelength. Get peaks where there is absorption emr=electromagentic radiation c=! Exciting oh of the water molecules in food! Energy absorbed in microwaves and dissipated with heat! Infrared-enough energy to cause a co bond to stretch/vibrate! X-rays bent in predictable way to show where atoms are in space! Organic molecules are getting excited instead of your molecules! Could decay tho and make other bad by products that is not good for you either! If you want energy of a mole of photons just multiply by planks constant! Visible light can cause bonds to break apart!
