Abstract
In this talk, I will review the status of infrared spectroscopy of molecules in planet-forming (Class II) disks from 20 years of data from ground- and space-based observatories. I will discuss multiple science angles from studying different kinematic components that trace gas in inner disk rings and winds at 0.01-10 au: their physical and chemical structure, kinematics, excitation, and evolution. I will also present spexodisks.com, a new database of infrared (1.4-35 um) spectra from VLT-CRIRES, IRTF-iSHELL, Keck-NIRSPEC, VLT-VISIR, Spitzer-IRS (and recently IGRINS too!) that is now available to the community in support of new observing and modeling efforts worldwide. I will conclude by demonstrating how the synergy of data from multiple instruments is supporting the analysis of JWST observations, in the context of the spectral range, molecular tracers, and resolving power that each instrument offers.
