Dr. Tokaryk developed an unexpected interest in molecular spectroscopy and physics during his graduate studies, when the group he was in led by his Ph.D. supervisor Dr. Robert L. Brooks observed spectra of the simple molecule helium hydride (HeH) from cryogenic samples of solid hydrogen doped with helium
excited with a high-energy beam of protons. 他在NRC的工作使他接触到了世界领先的分子科学家,并对天体物理分子产生了兴趣,比如C3,一种在分子云中检测到的线性碳链,以及其他外来物种,比如氢化氩(ArH)。 在UNB,他与dr。 Allan Adam和Colan Linton将他的专业知识扩展到含金属不稳定物种的激光光谱。 他的实验室最近对FeH(氢化铁)的研究对寻找围绕冷恒星的系外行星产生了影响,而对YbOH(氢氧化镱)的研究支持了对电子永久电偶极矩的研究。
当加拿大光源同步加速器启动时,托卡里克博士是团队的一员,该团队使用同步加速器的光作为探针,为气相分子的高分辨率傅里叶变换光谱建立了远红外光束线。 He is now the far-infrared line’s beam-team leader and has continued work on astrophysically-interesting molecules while pursuing other interests in small aromatic ring molecules. 他还研究了丙二醛和NCNCS等表现出大幅运动的分子。
