We investigate the dynamics of chromospheric mottles observed with THEMIS. We study a half an hour time series of 2-D intensity and Doppler velocity images at different wavelengths within the Hα line, obtained with the Multichannel Subtractive Double Pass (MSDP) spectrograph with a cadence of 40.5 sec. We determine the physical parameters in dark mottles with an inversion technique which is based on an iterative cloud model method with constant source function. With this method we calculate the optical thickness τmax, the Doppler width ΔλD, the velocity v and the source function S describing the structure. We discuss the results of the inversion technique and show the spatial and temporal evolution of several physical parameters along the axes of individual mottles. The pattern of the derived velocities as a function of space and time (time slice images) suggests the presence of magnetic reconnection as the driving mechanism of their formation.
