## Abstract Spatially localized lineshapes of hyperpolarized (HP) ^3^He in guinea pig lungs have been measured __in vivo__. Three different axial slice locations, each containing different compositions of airway sizes and orientations, were studied. Gas peaks from major bronchi (2 ppm) and alveoli

The high-field nonlinear NMR absorption signal of the B phase of 3He with an arbitrary orientation of the rotation axis n with respect to the field is calculated to third order in the amplitude of the perpendicular magnetization. An instability like those in ferromagnetic resonances is predicted, wh
We study an algebra of Poisson brackets of the Hamiltonian system defined by the nonlinear Leggett equations of spin dynamics in the A-and the B-phases of superfluid 3 He. For the A-phase the Poisson algebra results in a special case of the equations of motion of a rigid body in ideal fluid; for the
