WebChemical Shift. 13 C nuclei have a different value of g (the magnetogyric ratio) compared to 1H nuclei, so the resonance frequencies of 13C nuclei are different to those of protons in the same applied field (referring to formula 6.4, in section 6.5).In an instrument with a 7.05 Tesla magnet, protons resonate at about 300 MHz, while carbons resonate at about 75 MHz. WebIn this example, the total carbon footprint of a t-shirt by a particular brand is 3.3 kg of CO2. The figure, 3.3 kg CO2, is what we refer to as cradle to grave because it incorporates emissions for product use and disposable/end of life. Some carbon labels are cradle to gate which only include the emissions up until it’s sold, thereby emitting emissions from …
