The software should be able to do proxy authorization based on a username and password. The booleans proxySet and Authorization enable the use of a proxy and the use of authorization with that proxy. The proxyHost and proxyPort define the proxy server and the port by which it can be reached. In case Authorization is set true, the username and password parameters define your identity. If a connection to the internet is active, you can download 2D structures from the Internet into a new frame.
Indices are also determined dynamically, by querying the superdatabase.
Normally, CAS and NSC indices are expected. In most cases the structures downloaded by its NSC number result in a 2D projection of 3D structures. One should be aware that one-sphere hose codes are far to unprecise to give a decent estimate of the experimental chemical shift. You should take these values as what they are, namely expectation values for the chemical shift of a particular type of carbon atom environment. The predicted shifts are listed on the console.
