What part of the electromagnetic spectrum contains the majority of the suns rays?
IR, visible, UV. Our sun's radiation peaks in the yellow portion of the spectrum.
What is meant by a continuous spectrum?
You can use spectra to estimate the temperature of the star: astronomical thermometer
Why use KBr in FTIR?
The crystal has no visible peaks in the infrared spectrum making it transparent in ftir.
Why is the gas phase spectrum of benzene different from the liquid phase?
In the gas phase, benzene molecules act independently. Benzene molecules in the liquid phase are closer together than in the gas phase. They interact with each other and alter the molar absorptivity values. This causes the sharp peaks of the gas phase spectrum to broaden. Collisional broadening is also a factor in the liquid phase as well.
What is the traditional method of infrared spectroscopy?
Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample. For further details, see the links to the left of this answer.
What meant by an absorption spectrum?
In the absorption spectrum the peaks are due to preferential absorption at a definite wavelength by molecules, ions, etc.
Why are peaks important in spectroscopy?
In the field of spectroscopy absorption a peak means the wavelength of radiation where a sample absorbs. Different molecules absorb radiation of different wavelengths. An absorption spectrum will show a number of absorption bands, each one corresponding to structural groups within the molecule. Each band is represented by peak if you plot absorbance vs wavelength. By knowing which structural groups correspond to which peaks, you can often identify a compound by it's spectrum. For many molecules, the spectrum has been characterized, and you can use the spectrum to determine the purity, concentration, or other properties of the molecule by looking at the position and intensity of the peaks in the absorption spectrum.
What is the relation between the electromagnetic spectrum of solar radiation and the absorption spectrum of chlorophyll?
Solar radiation peaks in energy in the mid-yellow range. Chlorphyll's absorption also peaks in this range. It is a demonstration of the adaption of plants to optimizing their production efficiency.
The thermal spectrum that is produced by your body peaks in which part of the electromagnetic spectrum?
microwave
How many peaks will be present in a mass spectrum for?
There will be four peaks in the mass spectrum.
What portion of the spectrum does suns black body curve peak?
It peaks in the visible spectrum.
How many absorption peaks does chlorophyll a have?
P680 and P700 (both are red light) ;D
What part of the electromagnetic spectrum contains the majority of the suns rays?
IR, visible, UV. Our sun's radiation peaks in the yellow portion of the spectrum.
In the resolution nuclear magnetic resonance spectrum of methyl ethyl ketone how many peaks will appear?
4
Why IR spectrum peaks come down?
In IR spectrum we take percent transmittence on vertical axis and wavelength on horizontal axis, so the peaks come down i.e more the certain wavelength of IR have been absorbed more deep will be the peak that is less amount of light of that wavelength was transmitted.
What causes a multiplet in proton NMR?
Adjacent carbons have more than one H atom which causes splitting of peaks in the spectrum. Multiple peaks corresponding to one or more magnetically equivalent atoms are multiplets
Why is toluene in hexane used in uv calibration?
Toluene has clear absorption peaks at 266 nm and 269 nm. Hexane is only the solvent.
