Webthis paper, we discuss only the “absorption versus wavenumber” curves. In short, the IR spectrum is divided into three wavenumber regions: far-IR spectrum (<400 cm-1), mid-IR spectrum (400-4000 cm-1), and near-IR spectrum (4000-13000 cm-1). The mid-IR spectrum is the most widely used in the sample analysis, but far- and near-IR WebIf you were to look up - on a "table of characteristics of IR absorption" - you would see that a signal appearing at approximately 2100-2260 cm^-1 depicts a C-C triple bond (or an …
