Why can’ ’t we see microwaves? t we see microwaves? Why can Microwave Microwave I nfrared I nfrared Electromagnetic Spectrum – Absorption Percentage vs. Wavelength

Why do molecules absorb different Why do molecules absorb different wavelengths differently? wavelengths differently? Rotational Mode •Molecules rotate when they absorb radiation Vibrational Modes •Occurs at higher energy •Can combine rotational with different vibrational modes Symmetrical Stretching Symmetrical Stretching Scissoring Scissoring Asymmetrical Stretching Asymmetrical Stretching

Where does water vapor fit in? • Liquid phase condenses, scattering visible and infrared • Gas phase absorbs and emits in infrared and microwave spectra • Fluctuates spatially and temporally
