Why could the IR spectrum of a sample which is contaminated with water lead to an erroneous conclusion that the compound is an alcohol or a phenol?

Alcohols, phenols, and water all contain a hydrogen covalently bound to an oxygen.

What are Frequencies of light emitted by an element called?
"Spectrogram" is a word used to describe the set of specific characteristic frequencies of light which are emitted by a given chemical element when it is sufficiently excited by heat or by some other means.Alternatively, a scientific technique known as "spectroscopy" can be used to identify the elements in some matter of unknown composition and also the emission spectra of molecules can be used in chemical analysis of substances.Because each element's emission spectrum is unique, the "emission spectrum" of a chemical element or chemical compound can be used to help identify what it is. The "emission spectrum" is the name given to the relative intensity of each frequency of electromagnetic radiation http://www.answers.com/topic/emission-spectrum by the element's atoms or a compound's molecules when they are returned to a ground state.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
What spectrum is evidence for quantized change?
Line Spectrum
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
What does the term bright line spectrum mean?
There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
What has the greatest period in the electromagnetic spectrum?
the electromagnetic spectrum with the smallest frequency will have the greatest period.In conclusion, because Radio Waves have the lowest frequency they therefore have the greatest period.
Which part of the electromagnetic spectrum has the greatest period?
the electromagnetic spectrum with the smallest frequency will have the greatest period.In conclusion, because Radio Waves have the lowest frequency they therefore have the greatest period.
Is light a element compound or mixture?
It is none of these. Light is the visible part of the spectrum of electro-magnetic energy.
What is the mass spectrum for mz abudant value of 199 in isoflurane compound?
I am a bit confused by your question. Are you asking what gives rise to mz199 in the mass spectrum of isoflurane? Isofluorane has a MW of 184.5 and therefore wouldn't give rise to a peak at 199. Are you sure this is the right compound or that there no other impurities present? I am a bit confused by your question. Are you asking what gives rise to mz199 in the mass spectrum of isoflurane?

What are the strengths of infrared spectrometry?
Infrared spectrometry can provide a complex fingerprint which is unique to the compound being examined. As its instruments as computer controlled, the matching of the spectrum of a compound to its standard fingerprint can be readily carried out.

What do you mean by long term spectrum?
bacause the spectrum means spectrum so the spectrum is known as spectrum is called as spectrum
What are the strengths of infrared spectroscopy?
Infrared spectroscopy is capable of providing a complex fingerprint region which is unique to the compound being examined. This allows the compound to be identified by matching its sample spectrum to the standard. Computer control of instruments also allows this to be readily carried out.

What is main difference between prism spectrum and grating spectrum?
Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
Is an absorption spectrum also called a bright line spectrum?
No, its an absorption spectrum
