I must say Orange has really done great job in the world of machine learning. I have 3 questions.

(1) I have found "Orange Infrared" has been added recently. But I haven't found any kind of data regarding infrared spectra. I would like to know how to get that Infrared data? Whether the IR spectra data from Gaussian software can be used to be trained in Orange?

(2) I have seen a video orange has Neural Network classifier, But I downloaded and installed orange 3.3.12, No neural network model has been found.

(3) What is CN2 rule Induction, by any means is it related to Convolution Neural Network.

An infrared data set "Collagen spectroscopy" is available in the "Data Sets" widget. There are some other but small data sets in the infrared data folder: the easiest way to find the folder is to search for "peach_juice.dpt".

Orange Infrared can read Opus, Envi, .spa, .nea, Omnic maps, and some ASCII file formats.

Neural Network became available to Orange recently. The version that you have does not have it, and you have to install a newer version (say, the most recent version 3.6.0). Neural Network can be used both for regression and classification, in typical Orange workflow such as that for accuracy estimation with cross-validation (shown below) or class prediction (using Predictions widget.
