We present the results of high-resolution near-IR spectroscopy toward the multiple outflows around the Herbig Be star LkH { \alpha } 234 using the Immersion Grating Infrared Spectrograph ( IGRINS ) .
Previous studies indicate that the region around LkH { \alpha } 234 is complex , with several embedded YSOs and the outflows associated with them .
In simultaneous H - and K - band spectra from HH 167 , we detected 5 [ Fe ii ] and 14 H _ { 2 } emission lines .
We revealed a new [ Fe ii ] jet driven by radio continuum source VLA 3B .
Position-velocity diagrams of H _ { 2 } 1 - 0 S ( 1 ) \lambda 2.122 \micron line show multiple velocity peaks .
The kinematics may be explained by a geometrical bow shock model .
We detected a component of H _ { 2 } emission at the systemic velocity ( V _ { LSR } = - 10.2 km s ^ { -1 } ) along the whole slit in all slit positions , which may arise from the ambient photodissociation region .
Low-velocity gas dominates the molecular hydrogen emission from knots A and B in HH 167 , which is close to the systemic velocity , [ Fe ii ] emission lines are detected at farther from the systemic velocity , at V _ { LSR } = - 100 - - 130 km s ^ { -1 } .
We infer that the H _ { 2 } emission arises from shocked gas entrained by a high-velocity outflow .
Population diagrams of H _ { 2 } lines imply that the gas is thermalized at a temperature of 2,500 - 3,000 K and the emission results from shock excitation .
