The problem is as follows:

A particular molecule is used as a quantum bit (qubit) in a nuclear magnetic resonance (NMR) quantum computer. The molecule has two possible energy states that can be used to encode information. The frequency difference between these two energy states is 7.9 MHz.

Suppose we want to apply a Hadamard gate to this qubit. The Hadamard gate transforms the |0⟩ state into the |+⟩ state, which is a superposition of |0⟩ and |1⟩ states. In an ideal quantum computer, this gate would transform the |1⟩ state into the |-⟩ state, which is also a superposition of |0⟩ and |1⟩ states. However, in the NMR setup, this transformation has some limitations.

Determine the specific limitations of applying the Hadamard gate in NMR quantum computing and how to overcome these limitations.
