The following code …A "frozen core" is used to freeze "core" electrons from correlating. There's no correlation in HF calculations, so it would make sense for a frozen core to only have a visible effect on post-HF calculations, which the code that you've shown doesn't specify at all. Apart from that, there seems to be an index out of bounds which suggests a bug in ...Dim list As System.Collections.ObjectModel.

An Input/Output (I/O) Stream represents an input source or an output destination. A stream can represent many different kinds of sources and destinations, including disk files, devices, other programs, and memory arrays. Streams support many different kinds of data, including simple bytes, primitive data types, localized characters, and objects. FileIO Implementations. Iceberg also has multiple FileIO implementations, but broadly these can be broken down into two categories as well: HadoopFileIO and native FileIO implementations.
