The word "FTIRATR" may seem difficult to spell at first glance, but with the help of the International Phonetic Alphabet (IPA), its spelling becomes clearer. The IPA phonetic transcription for "FTIRATR" is /ɛf ti aɹ eɪ ti ɑr/ which represents its individual sounds. Each letter in the acronym stands for a different component in Fourier-transform infrared attenuated total reflection, a scientific technique used to study the infrared absorption of thin films. So next time you come across this word, remember to break it down and sound it out using IPA!
FTIR-ATR stands for Fourier Transform Infrared-Attenuated Total Reflection. It is a spectroscopic technique used to analyze materials by measuring the interaction between infrared radiation and a sample.
The term "Fourier Transform Infrared" refers to the type of spectroscopy employed in this technique. It involves the measurement of the absorption and transmission of infrared light by a sample. This helps to ascertain the chemical composition, functional groups, and molecular structures present within the material under investigation. Fourier Transform Infrared spectroscopy is highly accurate and precise, as it provides a wide range of spectral information.
The abbreviation "ATR" stands for Attenuated Total Reflection. It refers to the sampling technique used in FTIR-ATR spectroscopy. In this method, an infrared beam is focused onto the surface of the sample at a specific angle. The beam penetrates a short distance into the material, resulting in an attenuated reflection of the beam. This attenuated reflection is measured and used to generate an absorption spectrum, providing valuable information about the sample's properties.
In summary, FTIR-ATR spectroscopy is a powerful analytic technique that utilizes Fourier Transform Infrared spectroscopy in conjunction with Attenuated Total Reflection to obtain detailed information about the molecular composition and structure of a material. By analyzing the absorption and transmission of infrared light, it enables scientists to identify and characterize the chemical components present in a sample.
