Understanding the spectrum of CH$\mathrm{5+}$ is a problem of long standing interest. Of particular interest is gaining a better understanding of the two high resolution spectra; one observed by White et. al {}}, and one that is partially assigned observed by the Nesbitt group. {}} Using excited state Diffusion Monte Carlo techniques in combination with symmetry adapted linear combinations of the internal coordinates of CH$\mathrm{5+}$, obtained from group theoretical analysis of the G$\mathrm{<mrow\; data-mjx-texclass="ORD">240</mrow>}$ CNPI group, we investigate the nature of the vibrationally, and rotationally excited states of CH$\mathrm{5+}$. By probing CH$\mathrm{5+}$ using these methods, we find that we are able to gain insights into the effects of the internal rotor motions of vibrationally excited states of CH$\mathrm{5+}$.
