I am looking for mass spectra (preferably GC/MS EI but will be also thankful for any other type of mass spectra) of the following compounds:
1. donepezil, CAS 120014-06-4;
2. 1-benzyl-4-(chloromethyl)piperidine, CAS No:67686-03-7 or 136704-10-4
3. 3-(4-hydroxy-3-methoxyphenyl)propanal, CAS 80638-48-8

Also I will be grateful for providing me GC retention indices of them (in n-alkane scale).

I am going to make synthesis of three of them and once I measure the GC/MS data I am ready to share them in return.

For those who are interested in contact with me this is my email address:

There is an EI spectrum of Donepezil in NIST 11. There are also two IT MS2 spectra for this compound in the NIST 11 MSMS Database.

There is an EI mass spectrum of β-(4-Hydroxy-3-methoxyphenyl) propionic acid in NIST 11.

If you get spectra of these compounds, NIST would be interested.

Dear David,
Thank you for your post and information that some spectra I am looking for are present in NIST 11 library. Unfortunately I do not have this library and I do not know when and if at all I will have an access to this version. I got donepezil and I am in the process of measuring of the GC/MS EI spectrum as well as n-hydrocarbon based RI of this chemical. Once I get those data I am going to deliver them to Gary Mallard/Ed White of NIST.
If you would like to contact me directly my email address msokolow05@hotmail.com was given in my original post.
