 Abstract: The development of hyperpolarization technologies enabled several yet exotic NMR applications at low and Ultra‐Low Fields (ULF), where without hyperpolarization even the detection of a signal from analytes is a challenge. Here we present a method for the simultaneous excitation and observation of homo‐ and heteronuclear multiple quantum coherences (from zero up to the third‐order), which give an additional degree of freedom for ULF NMR experiments, where the chemical shift variation is negligible. The approach is based on heteronuclear COrrelated SpectroscopY (COSY); its combination with a phase‐cycling scheme allows the selective observation of multiple quantum coherences of different orders. The nonequilibrium spin state and multiple spin orders are generated by Signal Amplification By Reversible Exchange (SABRE) and detected at ULF with a Superconducting QUantum Interference Device (SQUID)‐based NMR system.
