This invention concerns a process for producing oxide thin film on a substrate by an ALD type process. The polymer or resin is an aromatic polymer or a precursor thereof and the mixture is a neat mixture or is combined with a solvent. The ration of gyration of the pedal can be varied by sliding the pedal along the guide axle andor telescoping the guide axle relative to the fixed axle. In further aspects, the generated historical information is used to aid in making a subsequent switch to an alternate channel.
