When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular \u2018fingerprint\u2019 of the sample. The usefulness of infrared spectroscopy arises because different chemical structures (molecules) produce different spectral fingerprints.  The Fourier Transform converts the detector output to an interpretable spectrum. The FTIR generates spectra with patterns that provide structural insights.<\/p>\n\n\n\n<p>Dive deeper into these subjects by watching these three tutorials.<\/p>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-three-part-video-series\">Three-Part Video Series<\/h2>\n\n\n\n<p>&nbsp;This three-part video series teaches the basics of the most common <a href=\"https:\/\/www.thermofisher.com\/us\/en\/home\/industrial\/spectroscopy-elemental-isotope-analysis\/molecular-spectroscopy\/fourier-transform-infrared-spectroscopy\/resources.html?icid=CAD_blog_materials_2015Nov#academy\" target=\"_blank\" rel=\"noopener\">FTIR<\/a> sampling technique: <a href=\"https:\/\/www.thermofisher.com\/blog\/materials\/the-attenuated-total-reflection-atr-technique-for-analyzing-plastics?icid=CAD_blog_materials_2015Nov\" target=\"_blank\" rel=\"noopener\">Attenuated Total Reflection<\/a> (ATR).<\/p>\n\n\n<style>.wp-block-kadence-spacer.kt-block-spacer-6067_ab1c8d-95 .kt-block-spacer{height:60px;}.wp-block-kadence-spacer.kt-block-spacer-6067_ab1c8d-95 .kt-divider{border-top-width:1px;height:1px;border-top-color:#eee;width:80%;border-top-style:solid;}<\/style>\n<div class=\"wp-block-kadence-spacer aligncenter kt-block-spacer-6067_ab1c8d-95\"><div class=\"kt-block-spacer kt-block-spacer-halign-center\"><hr class=\"kt-divider\" \/><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-7-minute-video-the-basics-of-the-attenuated-total-reflection-technique\"><strong><a href=\"https:\/\/www.youtube.com\/watch?v=paZS5gv3P8g&amp;list=PLMiikclf3GL4ZAFqfux1tR1pyYmS4AkjR&amp;index=1&amp;pp=iAQB\" target=\"_blank\" rel=\"noreferrer noopener\">7-Minute Video: The Basics of The Attenuated Total Reflection Technique<\/a><\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/www.youtube.com\/watch?v=paZS5gv3P8g&amp;list=PLMiikclf3GL4ZAFqfux1tR1pyYmS4AkjR&amp;index=1&amp;pp=iAQB\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" src=\"http:\/\/admin.acceleratingscience.com\/wp-content\/uploads\/2015\/11\/atrbasicsvideo1.jpg\" alt=\"\" \/><\/a><\/figure>\n\n\n\n<p>This is the first video in a series that teaches the basics of the most common FTIR sampling techniques: Attenuated Total Reflection (ATR).&nbsp; How do people use ATR and why?&nbsp; Find out in this classroom-style instruction video.&nbsp; In less than seven minutes, I\u2019ll show you how infrared light moves through diamond and germanium crystals, what affects the depth of penetration can have on the sample, and the most critical things to consider when choosing between crystals.<\/p>\n\n\n\n<p>Which crystal should you use for Carbon Black Rubber?&nbsp; View the ATR-Basics <a href=\"https:\/\/www.youtube.com\/watch?v=paZS5gv3P8g&amp;list=PLMiikclf3GL4ZAFqfux1tR1pyYmS4AkjR&amp;index=1&amp;pp=iAQB\" target=\"_blank\" rel=\"noreferrer noopener\">video<\/a> and find out.<\/p>\n\n\n<style>.wp-block-kadence-spacer.kt-block-spacer-6067_211454-06 .kt-block-spacer{height:60px;}.wp-block-kadence-spacer.kt-block-spacer-6067_211454-06 .kt-divider{border-top-width:1px;height:1px;border-top-color:#eee;width:80%;border-top-style:solid;}<\/style>\n<div class=\"wp-block-kadence-spacer aligncenter kt-block-spacer-6067_211454-06\"><div class=\"kt-block-spacer kt-block-spacer-halign-center\"><hr class=\"kt-divider\" \/><\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-3-minute-video-the-atr-sample-preparation\"><strong><a href=\"https:\/\/www.youtube.com\/watch?v=UVRMlIc_B5w&amp;list=PLMiikclf3GL4ZAFqfux1tR1pyYmS4AkjR&amp;index=11&amp;pp=iAQB\" target=\"_blank\" rel=\"noreferrer noopener\">3-Minute Video: The ATR Sample Preparation<\/a><\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-image\"><a href=\"https:\/\/www.youtube.com\/watch?v=UVRMlIc_B5w&amp;list=PLMiikclf3GL4ZAFqfux1tR1pyYmS4AkjR&amp;index=11&amp;pp=iAQB\" target=\"_blank\" rel=\" noreferrer noopener\"><img decoding=\"async\" src=\"http:\/\/admin.acceleratingscience.com\/wp-content\/uploads\/2015\/11\/atrsampleprepvideo2.jpg\" alt=\"\" \/><\/a><\/figure>\n\n\n\n<p>This is the second video in a series that teaches the basics of the most common FTIR sampling techniques: Attenuated Total Reflection (ATR).&nbsp; This video addresses ATR accessories and sample preparation.
