and keypad; double bond zone; 1500 - 1000 cm-1 bond zone. According to the absorption characteristics, it can be divided into functional areas (4000 - 1300cm-1) and fingerprint areas (1300 - 600cm-1). The characteristic absorption peak of the group usually appears in the functional group...
FTIR can be a single purpose tool or a highly flexible research instrument. With the FTIR configured to use a specific sampling device – transmission or ATR for instance – the spectrometer can provide a wid...

molar absorption coefficient 1.35 × 10 5 l/mole/cm and a Beer's law range from 0.084‐1.26 ppm. 6‐Mercaptopurine TTC forms a stable deep yellow colored complex with λ max 345 nm, molar absorption coefficient 6.9 × 10 5 l/mole/cm and a Beer's law range from 0.0319 ppm to 3.519 ...
2-3 bands of this range are commonly used to confirm the existence of aromatic rings and hetero aromatic rings. (F) X-H in-plane bending vibration and X-Y stretching vibration zone (1475-1000cm-1); The region mainly includes C-H in-plane bending, C-O and C-X ...
functional groups in an organic molecule. Functional groups have vibration frequencies that are characteristic of that functional group. These vibration frequencies fall with the infrared (IR) frequency range. As such, passing an IR signal through the organic compound causes the functional groups to ...
Along with the trusted high-performance optics and user-friendly interface of the OMNIC Paradigm Software, the Nicolet Summit PRO FTIR Spectrometer supports a range of useful features: Integrated computer:Save space and money when you run the OMNIC Paradigm Software on the built-in Windows 1...
Mid Infrared covers the region from about 200 to 5000 cm-1 Our FT spectrometers allow us to measure transitions from the visible (25,000 cm-1) through the far-IR (50 cm-1) spectral range. These regions yield specific information regarding functional groups, their associations and relative ...
The Fourier transform infrared (FTIR) and FT-Raman spectra of 4-methyl-1,3-dioxolan-2-one and 4,5-dichloro-1,3-dioxolan-2-one have been recorded in the range 3700–400 and 3700–100 cm−1, respectively. The complete vibrational assignment and analysis of the fundamental modes of the ...
FTIR analysis measures the range of wavelengths in the infrared region that are absorbed by a material. This is accomplished through the application of infrared radiation (IR) to samples of a material. The sample’s ability to absorb the infrared light’s energy at various wavelengths is measured...
