New input: The M+1 peak in mass spectrometry is due to an isotope of this element. An isotope of this element is used in a form of NMR which uses DEPT to determine chemical shifts between 0 and 220 ppm. Three alpha particles are transformed into an isotope of this element in the triple-alpha process. The mass of one dalton is defined based on the mass of one of this element's isotopes. The natural logarithm of two, divided by 5700, gives the rate constant in inverse-years for a process undergone by an isotope of this element. A mole is defined as twelve grams of its most common isotope. For 10 points, name this element used in radioactive dating, which normally has six neutrons.
