A C5HPD/FG probe is a quadruple-resonance probe which can irradiate RF pulses for ¹³C, ¹H, ³¹P, and ²H at once. For phosphorus-containing compounds, ¹³C signals may split due to couplings with adjacent ³¹P nuclei, and decoupling for ³¹P as well as ¹H using a C5HPD/FG probe makes ¹³C spectra simple (Example 1). Also, this probe allows for measurements of ¹³C-³¹P correlation spectra (Example 2). Thus, a C5HPD/FG probe is useful for analyzing phosphorus-containing compounds.
