The carbonyl stretch C=O of saturated aliphatic aldehydes appears from 1740-1720 cm-1.As in ketones, if the carbons adjacent to the aldehyde group are unsaturated, this vibration is shifted to lower wavenumbers, 1710-1685 cm-1.See also:

Pomocí ní se dnes zkoumají vlastnosti mnoha polovodičových materiálů, dále tzv. Historie. Zakladatelem spektroskopie je Jan Marek Marci a po něm sir Isaac Newton, pomocí optického hranolu objevil monochromatické světlo.Také si všiml, že čím čistější monochromatické světlo získává, tím slabší je jeho intenzita. IR Spectrum Table by Frequency Range. Use this table when you already know the frequency of your material.

Ir spektroskopie

This is a very useful tool for interpreting IR spectra: Only alkenes and aromatics show a C-H stretch slightly higher than 3000 cm-1.Compounds that do not have a C=C bond show C-H stretches only below 3000 cm-1. 2003, Pocket/Paperback.
