The infrared spectrum of triphenylmethanol will have a broad peak for the OH group at 3550 - 3200 cm^-1. It will also have a C-O peak at 1300 - 1000 cm^-1. Because of the aromatic C=C groups in the three benzene rings, there will be prominent peaks around 1600 - 1585 cm ^-1 and 1500 - 1400 cm^-1.
OH should be approximately 3200-3550 cm-1. It must be very broad. The triphenylmethanol will more than likely have a slight stretch with the steric playing around.
Sorry for the bad spelling, had to take a few characters out for the question to fit in
Chlorophyll is necessary in photosynthesis, because: 1. it absorbs the light necessary for photosynthesis mostly the blue and red light but poorly in green light because of electromagnetic spectrm 2. gives the leaves it green color
Normal (non-coherent) light IS visible in air, just not too noticeably. If something is "visible" then that means specifically that "visible light" (aka light in the visible spectrm) is reaching your eyes. Lasers are only special because instead of being many wavelengths of light, they only emit one wavelength of light. And if that particular wavelength is not in your area then you will see that one more than others. Notice that a laser "tints" the wall red. If you put a red laser on a blue wall then you will see purple dot; etc.. That's why you see the sunset when the sun is no longer in view, the light being scattered by the air and the particles in the air. It's also why the sky is blue, with blue light being scattered by the atmosphere more than the red. But that aside, a low power red laser is not very visible in the air since the longer wavelength of the red light doesn't scatter well off the air molecules. Larger dust or smoke particles in the air can reflect the low power red laser and you see the twinkling effect as the beam hits the individual particles. On the other hand, a the shorter wavelength of a blue-green laser scatters off the air molecules more effectively, so you can see the photons scattering off from the beam. A very high power laser in air is another story. It has sufficient energy to ionize the air within the beam (like a lightning channel) and this ionized air glows with its own emitted light.
