We present improvement and confirmation of identified frequencies andpulsation modes for the $\gamma$ Doradus star HD 189631. This work improvesupon previous studies by incorporating a significant number of additionalspectra and precise determination of frequencies. Four frequencies wereidentified for this star: $1.6774 \pm 0.0002$ d$^{-1}$, $1.4174 \pm 0.0002$d$^{-1}$, $0.0714 \pm 0.0002$ d$^{-1}$, and $1.8228 \pm 0.0002$ d$^{-1}$ whichwere identified with the modes ($l$,$m$) = ($1,+1$), ($1,+1$), ($2,-2$), and($1,+1$) respectively. These findings are in agreement with the most recentliterature. The prevalence of ($l$,$m$) = ($1,+1$) modes in $\gamma$ Doradusstars is starting to become apparent and we discuss this result.
