We present new Keck II NIRSPEC high-spectral resolution 1-5micron spectra of FUor, FUor-like and EXor objects. FUors are young eruptive variables with active accretion disks. The outbursts are thought to be caused by a increase in the stellar accretion rate from 1E-6 Msun/yr to 1E-4Msun/yr and last of order 102 yrs. FUor-like objects share many of the spectroscopic characteristics of FUors, though their outbursts have not been observed. EXors undergo shorter lived outbursts that are much less intense. We present the cross correlation of the NIR spectra of these objects as well as a detailed analysis of ro-vibrational CO fundamental and overtone lines, ro-vibrational H2O, ro-vibrational H2 and Br-gamma lines.
