WebThe common solvent acetone (C3H6O) has a C-O bond that strongly absorbs IR radiation at a wavelength of 5831 nm. If you have 25.0 mL of acetone in vial (D = 0.785 g/mL), how many kJ of energy can the acetone absorb of 5831 nm radiation assuming each molecule only absorbs one photon? E = hν = hc/λ h = 6.626 X 10-34 J·s c = 3.00 X 108 m/s NA = WebGreenhouse gases are gases in the Earth’s atmosphere that can absorb and emit radiation, primarily infrared radiation. The greenhouse gas that interacts with radiation across the largest number of wavelengths is water vapor (H 2 O), which interacts strongly with the atmosphere, especially in the longer wavelength portion of the spectrum. WebMolecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO 2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon. toby guy
