Our Raman data indicate a small discontinuity accompanied with continuity in the frequency shifts at $\simeq$ 1.6 kbar (tricritical). At $\simeq$ 2.8 kbar this discontinuity seems to disappear as the system changes its phase from a first order to a second order one. The Raman spectra of the $TA_{M}$ ($93 cm^{-1}$) mode of $NH_{4}Cl$ are presented.	en_US
