Magnetic octupole and scalar spin-spin interactions have been observed in I2127 by precisely measuring (line centers located to 1 part in 1011) the hyperfine spectrum on the P(13), 43-0 line using laser-molecular-beam techniques. The values of the coupling strengths obtained from fitting the spectrum are, for the electric quadrupole, eQq′=-554 094±13 kHz and eQq′′=-2 448 025±10 kHz; for the spin-rotation, C′-C′′=186.71±0.10 kHz; for the tensor spin-spin, Dt′-Dt′′=-100.5±1.0 kHz; for the scalar spin-spin, Ds′-Ds′′=-2.72±1.0 kHz; and for the magnetic octupole, Ωm′-Ωm′′=-2.17±0.70 kHz.
