title: How to store molecules in memory?
body: <p>I want to store molecules in memory. These can be simple molecules:</p>
  
  <pre><code>Methane (CH4)
  C-H bond-length: 108.7 pm
  H-H angle: 109 degrees
  </code></pre>
  
  <p>But also more complex molecules, like paracetamol (C8H9NO2):<br>

  <p>How can I store molecules in memory, including all bond-lengths and angles?</p>
  
  <hr>
  
  <p>A good idea to store atom-structs in an array? Or is there a better way?</p>
